Leo Hendrik Baekeland |
death Leo Hendrik Baekeland Died 23 Feb 1944 at age 80 (born 14 Nov 1863). Leo Henricus Arthur Baekeland was a Belgian-American industrial chemist who invented the first thermosetting plastic, Bakelite, that did not soften when heated. His first successful invention was Velox (in the 1890's), a photographic paper that could be used with artificial light rather than sunlight, which he sold in 1899 to George Eastman for $1 million. He then experimented to find a synthetic substitute for shellac, a useful insulator of wires in electric coils. Eventually, he was able to control heat and pressure for a formaldehyde-phenol reaction. By 1909, he displayed the world's first fully synthetic plastic, which could be used not only for insulators, but moulded into buttons, knobs and countless other items. With this patented product, he helped found the modern plastics industry. |

Sir Charles Vernon Boys |
death Sir Charles Vernon Boys Died 30 Mar 1944 at age 89 (born 15 Mar 1855). English physicist and inventor of sensitive instruments. His studies included in mining, metallurgy, chemistry and physics. He was also self-taught in a wide knowledge of geometrical methods. In 1881, he invented the integraph, a machine for drawing the antiderivative of a function. Boys is known particularly for his definitive book (1890) on the physics soap bubbles. He employed the torsion of quartz fibres to measure minute forces, repeating (1895) Henry Cavendish's experiment, to improve the measurement of the Newtonian gravitational constant. He also invented an improved automatic recording calorimeter for testing city coal gas (1905) and high-speed cameras to photograph rapidly moving objects, such as bullets and lightning discharges. He was knighted in 1935. Upon retirement in 1939, he grew and studied garden weeds. |

Godfrey Wilson |
death Godfrey Wilson Died 19 May 1944 (born 1908). British anthropologist and analyst of social change in Africa. As first director of the Rhodes-Livingstone Institute in Zambia, he theorized that the social problems in Africa were the products of colonialism and that the processes of industrialization and labor migration encompassed these social problems. His study of the cattle owning Nyakyusa of the Southern Highlands Province of Tanganyika Territory was made in 1936. It is much concerned with an account of marriage customs and sex relations, and described the peculiar traditional chiefdom. He committed suicide, as a conscientious objector in WW II. |
