Dr. Edwin Seaborn was born on May 14, 1872 in Rawdon, Quebec to Reverend William Minter Seaborn and Aquile Rondeau Seaborn. The family moved to London, Ontario in 1879. Seaborn graduated from Western University Medical School in 1895. After graduation he taught Anatomy at the Medical School, becoming a professor of Anatomy and Surgery and the Chair of Anatomy by 1916. In 1916, Seaborn was appointed commander, at the rank of Lieutenant-Colonel, of the No. 10 Stationary Hospital established by Western University. The unit served in England from 1916 to 1917, and France from 1917 until demobilization in 1919.
In private practice in London after the war, Seaborn also carried out medical and zoological research. His research included an extensive study of Ochronosis, a rare disease, and a study of the Maskinonge species of fish. Seaborn was also interested in local history. He was very active in the London and Middlesex Historical Society, and served as president in 1936. Through his involvement in the society, he obtained access to the diaries, letters and reminiscences of various area residents, including early pioneers, farmers, merchants and doctors. Seaborn combined his love of medicine and history, to write The March of Medicine in Western Ontario, which traces the history of medicine in Western Ontario. In 1938, the University of Western Ontario presented Seaborn with an Honorary Doctor of Laws degree.
In 1904 Seaborn married Ina Matilda Bucke, daughter of prominent physician, Dr. Richard Maurice Bucke. They had one child, Ina (Dee-Dee) Jessie Helene.
Edwin Seaborn retired in 1948 and died in London, Ontario in November, 1951.
