William Henry Coop was born in Portis, Osborne County, Kansas on May 22, 1935.  The son of Henry and Dorothy (Hoel) Coop, William moved around quite a lot in his life, living in Oregon, Washington, California, Ohio, Oklahoma, and Texas in addition to Kansas.

He spent the majority of his career in several prestigious aerospace industry leadership roles before co-founding the Entronics Corp of Dallas, Texas in 1984 with his wife, Nora (Adams) Coop.  The couple were also certified commercial pilots who raised two children, William and Kathryn.

William’s aerospace achievements peaked in the 1970s when he led the team of engineers responsible for the design and deployment of the soil sampling equipment for NASA’s two Viking Explorer spacecraft that successfully landed on Mars in 1975.  William’s name is engraved on plaques attached to both Viking Landers, which still remain today on the surface of the Red Planet.

In later years the Coops moved to Camas, Clark County, Washington, where William passed away on June 23, 2012.  He was laid to rest in the Fern Prairie Cemetery at Camas, Washington.

BIOGRAPHY:

Michael W. DrydenMichael W. Dryden was born on May 12, 1959 in Osborne, Kansas.  Mike’s parents are Dixie (Pierce) Blunt and Victor Dryden (1933-1986).  His mother was born and raised in Osborne and his dad was born and raised in Stockton, Kansas.  Mike went to elementary school and middle school in Osborne and Downs, Kansas .  Mike is a 1977 graduate of Waconda East High School in Cawker City, Kansas.  Mike was an excellent student athlete in high school and was honored to receive 1st Team All-State in football his senior year.

It was in high school that he met and started dating Joan Winkel from Glen Elder, Kansas and the two were married in 1979.   Following graduation from high school in May of 1977, Mike attended Kansas State University majoring in Wildlife Biology.  He was accepted into the College of Veterinary Medicine at Kansas State University in the fall of 1980.  Mike was awarded his Bachelor of Science Degree in 1982 and his Doctor of Veterinary Medicine Degree in 1984.

After graduating from the College of Veterinary Medicine, Mike, Joan and their son Shawn moved to Beloit, Kansas, where in May of 1984 Mike worked as a mixed animal practitioner with Dr. Charles Luke at the Solomon Valley Veterinary Hospital.  Mike, Joan and Shawn moved to Wichita, Kansas where he was employed in August 1985 as a small animal practitioner at Bogue Animal Hospital West.

Then in July 1986 Mike was accepted as a Graduate Research Assistant in Veterinary Parasitology at Purdue University’s College of Veterinary Medicine in West Lafayette, Indiana.  Mike, Joan and Shawn moved to West Lafayette in August 1986.  Their daughter Sarah was born while they were at Purdue.  During his graduate program at Purdue his studies included both Veterinary Parasitology and Medical/Veterinary Entomology.  With his primary research focus being the biology of fleas infesting dogs and cats.  He was in fact the first veterinarian in the world to get a doctorate studying flea biology.  At Purdue University Mike earned both a MS (May 1988) and a PhD (May 1990) in Veterinary Parasitology.  It was while a graduate student at Purdue that the veterinary students started calling him “Dr. Flea.”

Upon completion of the graduate program Mike accepted an offer from the College of Veterinary Medicine at Kansas State University and in June of 1990 Mike, Joan, Shawn and daughter Sarah moved to Manhattan KS.

Mike is recognized as a passionate educator.  He co-taught the Veterinary Parasitology course in the College of Veterinary Medicine from 1990 to 2001 and became course coordinator in 2002 and has been a guest lecturer in several other courses.  In 2010 along with Dr. Patricia Payne he developed the “Evidenced Based Small Animal Clinical Parasitology Training Course” at Kansas State University.  The unique course is the first of its kind developed in the world.  This week long course is designed to provide technical service veterinarians working in industry and veterinarians in academia a comprehensive clinical education in the areas of the biology, epidemiology, treatment and control of fleas, ticks, mites, heartworms, and intestinal parasites of dogs and cats.  Since 2010 almost 100 veterinarians from the U.S., Canada, Australia and Europe have attended the course.  The course has become so popular that the sessions book up a year in advance.

At the College of Veterinary Medicine at Kansas State University Mike has developed a research program that has been involved in three primary areas: (1) biology and control of fleas and ticks infesting dogs and cats, (2) investigations into the interactions and disease transmission of urban wildlife with domestic pets and humans and (3) diagnosis and control of gastrointestinal parasites of dogs and cats.

Research projects in the area of flea and tick biology and control have constituted the majority of this research effort. His research team has conducted laboratory and field evaluations of prospective flea and tick products in Manhattan, Kansas and Tampa, Florida, including investigations of the largest selling flea and tick products in the world; ActivylÒ, AdvantageÒ, CapstarÒ, ComfortisÒ, FrontlineÒ plus, K9 AdvantixÒ, ProgramÒ, RevolutionÒ, SentinelÒ and VectraÒ 3D.

Conducting such a large research program has necessitated cooperative research with numerous faculty and students.  The team has co-authored research grants and publications with faculty and graduate students in the Departments of Clinical Sciences, Entomology, Biology and Electrical and Computer Engineering at Kansas State University.  He has also co-authored publications with numerous researchers at other Universities.

Mike was promoted to Full Professor in the Department Diagnostic Medicine/Pathobiology in the College of Veterinary Medicine at Kansas State University in 1999.  In addition he has adjunct professor status in the Department of Entomology, Kansas State University and the Center for Urban and Industrial Pest Management, Purdue University.

“The world has more than 2,000 different kinds of fleas, but there is only one species that commonly infests dogs and cats in North America. Americans spend more than $1.5 billion a year trying to fight this pest on their pets. Michael W. Dryden says people should know their enemy and not assume all flea products are created equal.

“Dryden is considered one of the world’s foremost experts on fleas and ticks that infest dogs and cats and was once the subject of a documentary about his work with fleas. He has been an expert source on fleas for The Wall Street Journal and ‘Good Morning America.’” – From Kansas State University Short Bios at http://www.k-state.edu/media/mediaguide/bios/drydenbio.html.

Dryden’s research has radically changed the veterinary profession’s understanding of flea and tick ecology.  In addition he has developed novel methods for evaluating flea and tick control products and proposed new concepts that revolutionized flea and tick control.  Virtually every major pharmaceutical company utilizes his laboratory and research team to help develop and evaluate their flea and tick control products.

In 2007 Mike was honored to receive an endowment from the Merial Corporation to establish the “Dryden-Merial Tick Research Center at Kansas State University”.  This endowment help fund a tick research laboratory and provide salary for an additional research technician.

Mike’s clinical parasitology research has generated over 125 basic and applied research journal articles, 8 book chapters and over 100 published scientific abstracts.  The importance of his research on the veterinary profession and his passion as an educator is exemplified by the fact that he has been invited to lecture in over 21 countries (many multiple times), presenting over 850 invited seminars at national and international scientific conferences, numerous colleges of veterinary medicine around the world and dozens of veterinary continuing education symposiums. His research has also received both National and International media recognition with Mike appearing in segments on Good Morning America, CBS This Morning, the Discovery Channel, Mona Lisa Productions in France, and televised appearances in Canada, England, and Spain, and interviews and articles in over 100 newspapers and magazines.

Mike has been recognized with numerous awards and honors.

Rodney Keith Heitschmidt – 2010 Inductee

From the Desk of Dr. Rod Heitschmidt

Heitschmidt Rodney portraitRodney Keith Heitschmidt, son of Harold and 1996 Osborne County Hall of Famer Wilma Heitschmidt, was born October 28, 1944 in Hays, Kansas.  He grew up on his parent’s farm, located three miles west of Covert, Osborne County, Kansas.  His family included an older brother Roger, and a younger sister Elaine.  His grandparents were Nick and Tillie Heitschmidt and Chris and Lovie Sigle.  His Grandpa and Grandma Heitschmidt lived about one mile northwest of his parents’ farmstead and his Grandpa and Grandma Sigle lived about three miles southeast of his parents’ farmstead.

Rod attended grade school in the two-room school in Covert. There were five in his 1959 8th grade graduating class: he; Steve Miller; Sandy Murphy; Gerald Mitchell; and Marilyn Wirth.  He attended high school in Paradise, Kansas, graduating in 1963 with seven classmates: Janice McNeal; Ken Stielow; Harold Robbins; Warren Eulert; Terry Hoopes; Don Landis; and Larry Weilert.  While in high school he was active in all sports, FFA, and choir.

Rod’s college education began in the fall of 1963 when he accepted a basketball scholarship from Fort Hays State University (FHSU) in Hays, Kansas.  He retired from basketball after his sophomore year when it became apparent to him that he was vying for one of the last bench warming positions for the mighty FHSU Tigers!

Rod married his high school sweetheart, Judy Sue Thompson, on August 21, 1965.  Shortly thereafter they moved into married couple housing—Wooster Place—on the FHSU campus.  Sue began working fulltime for Farmers State Bank and Rod part-time for Dr. Jerry Tomanek, Head of the Biology Department and later President of FHSU.  Rod completed his B.S. in Botany in 1967 and went on to complete his M.S. in 1968 under the guidance of Drs. Tomanek and Gary Hulett.  He then accepted a research assistantship at the University of Texas (i.e., Dr. Calvin McMillan) to pursue his Ph.D.

Rod and Sue moved to Austin, Texas in August 1968.  Shortly thereafter their first son, Jason Keith, was born (October 31, 1968).  At about the same time, Rod received a 1A rating from the Osborne County draft board.  After visiting with the local United States Air Force [USAF] recruiter, Rod agreed to join the USAF under a delay enlistment agreement.  Thus, he abandoned his studies at UT at the end of the first semester, accepted a position with the Texas Department of Agriculture’s Weights and Measures Laboratory while teaching a Biology 1 night class at UT.  In June 1969, Rod moved Sue and Jason to her parent’s home in Paradise before enlisting in the USAF.  His first tour of duty was as a candidate in the USAF Officer’s Training School at Lackland Air Force Base [AFB] at San Antonio, Texas.

Rod was commissioned as a 2nd Lieutenant in September 1969.  He, Sue and Jason then moved into a three-bedroom duplex at Columbus AFB, Columbus, Mississippi, for 52 weeks of flight training.  During this time, Rod and Sue’s second son, Dustin Lee, was born (June 17, 1970).  At the end of flight school, Rod was assigned the position of T-38 instructor pilot (IP) at Laughlin AFB, Del Rio, Texas.  However, before moving to Del Rio in March 1970, Rod attended two USAF schools.  The first was the Winter Survival & POW Training School at Fairchild AFB in Spokane, Washington.  Rod declared that to be a valuable school but not a very pleasant one.  The second school was T-38 IP training at Tyndall AFB in Panama City, Florida.

In March 1970, the family moved into a rented home in Del Rio.  Later that summer, they moved into a three-bedroom duplex on Laughlin AFB.  They resided in that home until Rod separated from the USAF in August 1974.

During his time in the USAF, Rod served as an IP in M Flight, as a squadron scheduler, and eventually as a member of the Wing Standardization and Evaluation team.  Rod and Sue’s decision to resign his commission and separate from the USAF was extremely difficult as both loved the USAF family. They found the pilots’ and their families’ comradery were extraordinary, fun, exciting and uplifting.  Their time in the USAF was one of the greatest experiences of their lives.

Rod separated from the USAF in August 1974 and entered graduate school at Colorado State University (CSU) in September. Rod’s research focused on quantifying the effects of sulfur dioxide, as emitted from coal-fired electrical generation plants, on grassland ecosystems.  To this end, the family spent the summers of 1975 and 1976 in a trailer house near Ashland, Montana, where Rod headed a crew of eight in the conduct of an array of grassland field research endeavors.

Rod’s research was funded via the Natural Resource Ecology Laboratory (NREL) at CSU.  He was officed in NREL and he considered himself a very lucky person to have had the experience of working with and learning from some of the finest grassland ecologists in the world.  One of the great things about NREL was that the mentors/professors treated graduate students as their equals. Working at NREL was truly a fun and exceptionally rewarding experience.

Rod graduated from CSU with his Ph.D. in rangeland ecology in August 1977.  He then accepted a position with the Texas Agriculture Experiment Station (TAES), part of Texas A&M University (TAMU).  He was officed near Vernon, Texas in the TAMU Chillicothe-Vernon Agriculture Research and Extension Center.  Although he worked at a number of sites across the Rolling Plains of Texas, his primary research site was the 3,600-acre Texas Experimental Ranch near Throckmorton.  The focus of his research was grazing management and closely associated disciplines. He was also a faculty member of the TAMU Department of Range Science.

In September 1990, Rod accepted the position of Research Leader of the 55,000-acre USDA Agriculture Research Service’s Fort Keogh Livestock and Range Research Laboratory (LARRL) near Miles City, Montana.  Research foci at LARRL were beef cattle genetics and reproduction physiology, range animal nutrition, and range ecology and management.  Rod’s research was focused largely on developing effective grazing/drought management tactics and strategies.  However, his primary job was “managing” the 50-member staff and the $4,000,000 budget.  For a more detailed understanding of the LARRL mission and operation, please visit www.larrl.ars.usda.gov/.

Rod retired from LARRL on December 31, 2006.  He and Sue have since moved to Pecan Plantation, a gated, golfing community located near Granbury, Texas.  Jason and his wife, Traci, and two children, Jarren (15) and Kacey (13), live in Flowermound, Texas.  Dustin died in a tragic automobile accident on October 14, 2004.  His widow, Wendy, and two children, Riley (14) and Reagan (10), live near Birmingham, Alabama.

Rod was a prolific writer throughout his career as he authored or co-authored 70-plus refereed journal articles, 50-plus book chapters and proceedings, 115-plus technical and popular articles and 85-plus abstracts.  In addition, he made over 135 invited presentations to scientific and lay audiences during his 29-year career.  He proudly served on many graduate student committees at both TAMU and Montana State University.

Rod has been the recipient of numerous professional awards including the Society for Range Management’s (SRM) Outstanding Achievement Award (1991), Fellow Award (2004) and Renner Award (2013).  He served as a Director and President (2002) of the SRM parent society, Director of the Texas section of SRM, and President (1997) of the Northern Great Plains section of SRM.  He received an Outstanding Instructor Pilot Award (1972) while serving in the USAF, the America/World Agriculture Award (2009) presented by the National Association of County Agricultural Agents, an Alumni Achievement Award from Fort Hays University (1997), and a Friend of Extension Award (2005) from the Montana State Agriculture Extension Service.
