About Jeremy Swan

Lived 1922 – 2005 (aged 82). Jeremy Swan was an Irish cardiologist, physician and inventor.

Harold James Charles “Jeremy” Swan (1 June 1922 – 7 February 2005) was an Irish cardiologist who co-invented the Swan-Ganz catheter with William Ganz at Cedars-Sinai Medical Center in 1970.

Early life and education Swan was born on 1 June 1922 in Sligo Ireland. His parents were both physicians, Harold John Swan and Marcella Bertile Swan née Kelly. His mother called him "Jeremy" to limit confusion and the name stuck throughout his life. Swan's early education was at Castle Rock School. He then attended St. Vincent's Castleknock College in Dublin and graduated in 1939. He attended medical school at Trinity College Dublin in Dublin but earned his degree from St. Thomas's Hospital, London, England graduating in 1945. Swan was also an intern and junior resident at St. Thomas's Hospital from 1945 to 1946. He then entered the Royal Air Force medical service from 1946 to 1948, being stationed in Iraq.

Career Swan worked as a cardiologist in the Mayo Clinic (in Rochester, Minnesota), and later moved to Cedars Sinai Hospital (Los Angeles). His description of the invention of the catheter is said to have derived from watching the wind playing with sails in Santa Monica. He was present at the Mayo around the time they were performing early open heart surgeries in the mid-1950s.
