Roma_Bahn

Roma Bahn (1896–1975) was a German stage and film actress. On stage she was notable for her performances as Polly in the original 1928 production of The Threepenny Opera. In cinema she played supporting roles in films made during the Weimar and Nazi eras.

Charles_Schmid

Charles Howard Schmid Jr. (July 8, 1942 – March 30, 1975), also known as the Pied Piper of Tucson, was an American serial killer whose crimes were detailed by journalist Don Moser in an article featured in the March 4, 1966, issue of Life magazine. Schmid's criminal career later formed the basis for "Where Are You Going, Where Have You Been?", a short story by Joyce Carol Oates.: 9  In 2008, The Library of America selected Moser's article for inclusion in its two-century retrospective of American true crime literature.

Erwin_Straus

Erwin Walter Maximilian Straus (11 November 1891, Frankfurt am Main – 20 May 1975, Lexington, Kentucky) was a German-American phenomenologist and neurologist who helped to pioneer anthropological medicine and psychiatry, a holistic approach to medicine that is critical of mechanistic and reductionistic approaches to understanding and treating human beings.
Some of his work can also be regarded as a precursor to or early version of neurophenomenology. Straus taught at Black Mountain College.
His books published in English include:

Phenomenology: Pure and Applied (1964, Duquesne University Press)
Phenomenological Psychology (1966, Basic Books)
Psychiatry and Philosophy (1969, Springer)
Phenomenology of Memory (1970, Duquesne University Press)
Language and Language Disturbances (1974, Duquesne University Press)
Man, Time, and World: Two Contributions to Anthropological Psychology (1982, Humanities Press)
On Obsession: A Clinical and Methodological Study (1987, Johnson Reprint Corp)

Foni_Tissen

Foni (Alphonse) Tissen (1909–1975) was a Luxembourg schoolteacher and artist who is remembered principally for his hyperrealistic, darkly humorous paintings, many of which were self-portraits.

Oskar_Perron

Oskar Perron (7 May 1880 – 22 February 1975) was a German mathematician.
He was a professor at the University of Heidelberg from 1914 to 1922 and at the University of Munich from 1922 to 1951. He made numerous contributions to differential equations and partial differential equations, including the Perron method to solve the Dirichlet problem for elliptic partial differential equations. He wrote an encyclopedic book on continued fractions Die Lehre von den Kettenbrüchen. He introduced Perron's paradox to illustrate the danger of assuming that the solution of an optimization problem exists:

Let N be the largest positive integer. If N > 1, then N2 > N, contradicting the definition of N. Hence N = 1.

Lucien_Godeaux

Lucien Godeaux (1887–1975) was a prolific Belgian mathematician. His total of more than 1000 papers and books, 669 of which are found in Mathematical Reviews, made him one of the most published mathematicians. He was the sole author of all but one of his papers.He is best remembered for work in algebraic geometry. From Liège, he was attracted to the work of the Italian school of algebraic geometry by the work of one of its masters, Federigo Enriques. Godeaux went to Bologna to study with him. The Godeaux surface is a construction of a special type, which has subsequently been much studied.
Since 2007, the Belgian Mathematical Society (BMS) is organising a "Godeaux lecture" in his memory.

Giuseppe_Colosi

Giuseppe Colosi (29 March 1892 – 20 October 1975) was an Italian zoologist. He specialized in the study of crustaceans and mysids in particular.
Colosi was born in Petralia Sottana. From 1920 to 1924, he taught in Turin, and he was the head of the zoological institute of the University of Florence from 1940 to 1962. He died in Florence, aged 83.
Colosi is commemorated in the scientific name of a species of lizard, Chalcides colosii.
