Ewing House

students high fivingDr. Sidney Ewing was a veterinarian with an insatiable desire to know more about parasites and anything outdoors, especially plants, singing birds, and invertebrate animals.  While famous for his contributions to the field of veterinary parasitology, service to others best describes Dr. Ewing, as he was known for his gentle spirit, mentorship, and devotion to family and friends.  Dr. Ewing was born in 1934 in Emory University, Georgia.  He received his BSA and DVM from the University of Georgia.  He completed his Master’s of Science degree from the University of Wisconsin prior to moving to Stillwater in 1960 to pursue a Ph.D. in veterinary parasitology under the direction of Dr. Wendell Krull.  In the 1960s, Dr. Ewing is quoted as describing research as detective work saying “you keep looking for clues, working to unravel something that is puzzling.” 

In 1964 Dr. Ewing and his colleagues (Dr. Ralph Buckner and Dr. Roger Panciera) discovered that dogs with babesiosis were co-infected with a second tick-borne agent, Ehrlichia canis. This was the first time anyone had ever seen an Ehrlichia in North America. In a 1971 publication, Dr. Ewing and colleagues described a new Ehrlichia strain that was present in granulocytes and would later be named E. ewingii in 1992. Throughout his career, Dr. Ewing taught and pursued research and administration at many land-grant institutions, including Oklahoma State, Kansas State, and Mississippi State Universities, as well as the University of Minnesota. His work at Oklahoma State spanned more than five decades.  His passion for the veterinary profession and OSU resulted in his continued attendance at seminars and meetings. He even taught a course on veterinary history after retirement. Dr. Ewing passed away in 2018, but not before he had left his mark on the veterinary profession and all who that had the privilege of knowing him.


The wolf symbolizes guardianship and loyalty. Similar to Dr. Ewing, their commitment and love of family is humbling, their communication skills elegant, and their extreme intelligence awe inspiring.


The color purple combines the calm stability of blue and the fierce energy of red. Representing ambition, creativity, wisdom, dignity, devotion, peace, and pride, there is no color that is better suited to represent the Ewing house.
