Warren William Marquardt, a poultry virologist and retired university professor, died Aug. 30 at Doctors Community Hospital in Lanham of myelodysplastic syndromes, a rare blood disorder. He was 75.

Dr. Marquardt was born Nov. 1, 1930, in Erhard, Minn. He graduated from Pelican Rapids High School and went on to play one year of freshman football at the University of Minnesota. He then attended and played baseball for Vallejo Junior College in California and played semipro baseball in Northern California.

Dr. Marquardt enlisted in the Air Force in 1951 and was stationed at Lackland Air Force Base in Texas for four years.

After being honorably discharged in 1955, he joined the University of Minnesota and earned a bachelor’s degree in science, a doctor of veterinary medicine degree, and a doctorate in microbiology and biochemistry.

Dr. Marquardt started his scientific career as a research fellow in veterinary microbiology at the University of Minnesota. He transferred to the University of Maryland as an associate professor in 1969 and went on to teach veterinary microbiology there and at Virginia Tech.

He retired as a full member of the graduate faculty at the University of Maryland at College Park in 1995 and was appointed professor emeritus to the Virginia-Maryland Regional College of Veterinary Medicine in 1996.

Dr. Marquardt was a well-known poultry virologist in serology and diagnostics. Along with his co-workers at the University of Maryland, he was internationally recognized for his work on the infectious bronchitis virus. The virus strain the group isolated in the lab, JMK, is the standard used in IBV vaccines.

The group’s poultry health management protocol is now a worldwide standard.

The scientists used single-serum sample from chickens to diagnose several poultry viruses and worked with a number of other poultry viruses.

Dr. Marquardt was an honorary member of the Phi Zeta (veterinary medicine), Gamma Sigma Delta (agriculture) and Sigma Xi (scientific research) societies.

Dr. Marquardt is survived by his wife of 51 years, Alice Marquardt of Mount Airy, Md.; two sons, Greg Marquardt of Owings, Md., and Steve Marquardt of Urbana, Md.; two daughters, Sheila Taylor of Sunderland, Md., and Cheryl Huston of Mount Airy; three sisters; two brothers and nine grandchildren.

Memorial donations can be made to the Myelodysplastic Syndromes Foundation, P.O. Box 477, 464 Main St., Crosswicks, NJ 08515.
