02 Feb 1913 Carl Gustaf Patrik de Laval	science	death Carl Gustaf Patrik de Laval Died 2 Feb 1913 at age 67 (born 9 May 1845). Swedish scientist, engineer and inventor who pioneered in the development of high-speed turbines. After earning his Ph.D. at age 27, he worked as a technical engineer at a steel mill in his home village. In 1877, he began developing a high-speed centrifugal cream separator, a significant advance in butter-making. He perfected a vacuum milking machine in 1913. About 1882, he began working on steam turbines, and by 1889, he applied for a British patent for an impulse type, with a jet of steam impinging on a set of blades around the periphery of a wheel. His inventive talent was wide, including electric lighting, electrometallurgy, and aerodynamics. During his lifetime, he acquired 92 Swedish patents and founded 37 companies.

13 Apr 1913 Robert Hingson	science	birth Robert Hingson Born 13 Apr 1913; died 9 Oct 1996 at age 83. American anesthesiologist and inventor known for three major inventions that continue to relieve pain and suffering worldwide today. One is a very portable respirator anesthesia gas machine and resuscitator, called the Western Reserve Midget, used to deliver a short-term, general anesthetic A second came from extensive experiments in the use of anesthesia to prevent pain during childbirth, leading to the invention of the continuous caudal anesthesia techniques. Best known is his "peace gun," a pistol-shaped jet injector that enabled efficient, mass, needle-less inoculation worldwide against such diseases as small pox, measles, tuberculosis, tetanus, leprosy, polio and influenza. It can inoculate 1,000 persons per hour with several simultaneous vaccines.

10 Aug 1913 Wolfgang Paul	science	birth Wolfgang Paul Born 10 Aug 1913; died 6 Dec 1993 at age 80. German physicist who developed the Paul trap, an electromagnetic device that captures ions and holds them long enough for study and precise measurement of their properties. During the 1950s he developed the so-called Paul trap as a means of confining and studying electrons. The device consists of three electrodes - two end caps and an encircling ring. The ring is connected to an oscillating potential. The direction of the electric field alternates; for half the time the electron is pushed from the caps to the ring and for the other half it is pulled from the ring and pushed towards the caps. For his work he shared the 1989 Nobel Prize for Physics with Hans Georg Dehmelt and Norman F. Ramsey.
