05 Feb 1973 John H. Gibbon	science	death John H. Gibbon Died 5 Feb 1973 at age 69 (born 29 Sep 1903). John Heyburn Gibbon was an American surgeon who invented the heart-lung machine. He was prompted when in 1930, as a Harvard research fellow in surgery, he saw a patient undergoing heart-lung surgery suffocate on his own blood. On 10 May 1935, he had built his first external pump, and was able to maintain the cardiac and respiratory functions of a cat. In the late 1940's, Gibbon received financial and technical assistance from the IBM Corporation to develop an oxygenator with sufficient capacity for a human. By 6 May 1953, with his improved machine he was able to perform the first successful open-heart operation - the repair of an atrial septal defect on 18-yr-old Cecelia Bavolek - maintaining the patient's heart and lung functions on the machine for 26 minutes.

23 Feb 1973 Dickinson W. Richards	science	death Dickinson W. Richards Died 23 Feb 1973 at age 77 (born 30 Oct 1895). American physiologist who was one of three who shared the 1956 Nobel Prize for Physiology or Medicine "for their discoveries concerning heart catheterization and pathological changes in the circulatory system". Richards helped develop the technique by which a catheter (a flexible tube) could be threaded through a vein into the heart to withdraw blood samples to determine cardiac abnormalities. In addition, it permits the measurement of blood pressure, blood flow or gas concentrations in various parts of the cardiac circulatory system (atrium, ventricles, or artery). This gives valuable information in the treatment of heart disease, defect or injury. Richards worked with André F. Cournand building on the original work of Werner Forssmann.

14 Mar 1973 Howard Hathaway Aiken	science	death Howard Hathaway Aiken Died 14 Mar 1973 at age 73 (born 9 Mar 1900). American mathematician who invented the Harvard Mark I, forerunner of the modern electronic digital computer. While a graduate student and instructor Harvard University, Aiken's research had led to a system of differential equations which could only be solved using numerical techniques, for which he began planning large computer. His idea was to use an adaptation of Hollerith's punched card machine. When eventually built, (1943) it weighed 35 tons, had 500 miles of wire and could compute to 23 significant figures. There were 72 storage registers and central units to perform multiplication and division. It was controlled by a sequence of instructions on punched paper tapes, and used punched cards to enter data and give output from the machine.

05 Dec 1973 Sir Robert Alexander Watson-Watt	science	death Sir Robert Alexander Watson-Watt Died 5 Dec 1973 at age 81 (born 13 Apr 1892). Scottish physicist who is credited with the development of radar location of aircraft, in England. He studied at St Andrews University, taught at Dundee University, and in 1917 worked in the Meteorological Office, designing devices to locate thunderstorms, and investigating the ionosphere (a term he invented in 1926). He became head of the radio section of the National Physical Laboratory (1935), where he began work on locating aircraft. His work led to the development of radar (RAdio Detection And Ranging) which played a vital role in the defence of Britain against German air raids in 1940. He was knighted in 1942.
