Edward Boyce Tuohy (1908 – 1959) was an American anaesthesiologist.
Best known for his contribution to developing continuous epidural anaesthesia through the introduction of the needle to which he gives his name, the Tuohy Needle
Controversy exists over whether Ralph L Huber was in fact the original inventor of the now ‘Tuohy needle’ and was never properly referenced in Tuohy’s original work.
Nonetheless, it was Tuohy that developed the use the Huber point for introduction of a catheter into the epidural space and his contribution to the development of continuous spinal epidural anesthesia cannot be disputed.

- WW II – Served in the US Army Medical Corps. Then returned to the Mayo clinic
- 1947 – Head of anesthesiology department, Georgetown Medical Centre, Washington DC

- 1951 – Professor of anesthesiology at the University of Southern California School of Medicine, Los Angeles

- Tuohy Needle – designed in 1944, original for continuous spinal anaesthesia
- The Tuohy needle was designed for use in continuous spinal anesthesia since and was first popularized in 1945. In Tuohy’s original work, in 1945, he describes a 15-gauge needle with ‘Huber point’ but he makes no reference to origin of the ‘Huber point’
- The term, however may be a misnomer with Ralph L. Huber (1890-1953), a Seattle dentist being the original inventor of the needle. In 1946, he applied for a patent on a needle with a ‘transversely curved wall…end portion’. Huber made many of his inventions available to the US Army during the war, including the Huber point which was adopted by the Army in 1942 and it is possible that Tuohy first encountered the Huber point during his time in the US Army.
