Dr. William Wyckoff Clark was an early physician and respected figure in the development of Mankato, Minnesota. A native of Pennsylvania, he later practiced medicine in Ashtabula County, Ohio, before moving west in 1858 and establishing himself in Mankato. He quickly built a large and active medical practice, serving a wide region of Southern Minnesota.
At the outbreak of the Civil War, Dr. Clark entered military service as an Assistant Surgeon with the 10th Minnesota Infantry. Commissioned on September 10, 1862, he served with distinction throughout the war and later rose to the role of Acting Division Surgeon in the 16th Army Corps. His service included involvement in the aftermath of the U.S.–Dakota War, where he was one of the physicians responsible for examining the bodies following the mass execution in Mankato to confirm death.
Following the war, Dr. Clark returned to Mankato, where his military experience elevated his reputation and further expanded his medical practice. He became one of the leading physicians in the region, known for both his professional skill and his personal character. He was associated in practice with the father of the Mayo physicians of Rochester and was regarded as a significant contributor to early medical care in Southern Minnesota.
Despite encouragement, Dr. Clark declined opportunities to enter political life, choosing instead to remain devoted to his profession. He continued practicing medicine until declining health forced his retirement in his final year.
Dr. Clark passed away on January 1, 1878, at the age of 56. His funeral was widely attended, reflecting the respect and esteem he held within the community. He was remembered as a skilled physician and a man of strong character who played an important role in the early development of Mankato.
At this time, no visible grave marker has been identified at his burial site in Glenwood Cemetery.
