Jean Marie Marcel Albert Pitres (26 August 1848 – 25 March 1928) was a French neurological physician. He was born in Bordeaux and received his training in Paris, where he was the student of Jean Martin Charcot (1825–1893) and Louis-Antoine Ranvier (1835–1922). He served as dean of the Faculty of Medicine at the University of Bordeaux – appointed 1885.
He began his medical studies in Bordeaux, later working as an interne to the hospitals of Paris (from 1872). In 1877, he defended his doctoral thesis, and during the following year received his agrégation with a dissertation titled "Les hypertrophies et les dilatations cardiaques indépendante des lésions valvulaires". In the late 1870s, with Charles-Émile François-Franck, he performed studies on the excitation of the cerebral cortex and the localization of brain function. Afterwards, he returned to Bordeaux, where from 1881 to 1919, he was maître to the chair of pathology. Pitres died in 1928, at the age of 79, after falling down stairs.
Lessons that Pitres gave at the amphitheater in Bordeaux on the following subjects were compiled and published: hysteria and hypnotism (1891), amnesic aphasia (1897), paraphasia (1898) and physical signs associated with pleural effusions (1902). His studies of peripheral neuritis were published in volume 36 of Augustin Nicolas Gilbert and Paul Carnot's Nouveau traité de médeine et de thérapeutique. With Leo Testut (1849–1925), he was co-author of Les nerfs en schémas, anatomie et physiopathologie (1925).
His name became associated with pleural effusion and with tabes dorsalis. The term "Pitres' sign" refers to hypoesthesia of the scrotum and testicles in tabes dorsalis.

Robert A. Trias (March 18, 1923 – July 11, 1989) was an American karate pioneer, founding the first karate school in the mainland United States and becoming one of the first known American black belts.

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.
