Technische Universität Berlin in the context of "Heinrich Martin Weber"

Franz Reuleaux (French: [ʁœlo]; German: [ʁøˈloː]; 30 September 1829 – 20 August 1905) was a German mechanical engineer and a lecturer at Technische Hochschule Berlin (today Technische Universität Berlin), later appointed as the president of the academy. He was often called the father of kinematics. He was a leader in his profession, contributing to many important domains of science and knowledge.

Today, he may be best remembered for the Reuleaux triangle, a curve of constant width that he helped develop as a useful mechanical form.

Alfred Messel (22 July 1853 – 24 March 1909) was a German architect at the turning point to the 20th century, creating a new style for buildings which bridged the transition from historicism to modernism. Messel was able to combine the structure, decoration, and function of his buildings, which ranged from department stores, museums, office buildings, mansions, and social housing to soup kitchens, into a coherent, harmonious whole. As an urban architect striving for excellence he was in many respects ahead of his time. His best known works, the Wertheim department stores and the Pergamon Museum in Berlin, reflect a new concept of self-confident metropolitan architecture. His architectural drawings and construction plans are preserved at the Architecture Museum of Technische Universität Berlin.

Leo Szilard (/ˈsɪlɑːrd/; Hungarian: Leó Szilárd [ˈlɛoː ˈsilaːrd]; born Leó Spitz; February 11, 1898 – May 30, 1964) was a Hungarian-born American physicist, biologist and inventor who made numerous important discoveries in nuclear physics and the biological sciences. He conceived the nuclear chain reaction in 1933, and patented the idea in 1936. In late 1939 he wrote the letter for Albert Einstein's signature that resulted in the Manhattan Project that built the atomic bomb, and then in 1945 wrote the Szilard petition asking president Harry S. Truman to demonstrate the bomb without dropping it on civilians. According to György Marx, he was one of the Hungarian scientists known as The Martians.

Szilard initially attended Palatine Joseph Technical University in Budapest, but his engineering studies were interrupted by service in the Austro-Hungarian Army during World War I. He left Hungary for Germany in 1919, enrolling at Technische Hochschule (Institute of Technology) in Berlin-Charlottenburg (now Technische Universität Berlin), but became bored with engineering and transferred to Friedrich Wilhelm University, where he studied physics. He wrote his doctoral thesis on Maxwell's demon, a long-standing puzzle in the philosophy of thermal and statistical physics. Szilard was the first scientist of note to recognize the connection between thermodynamics and information theory.

Eugene Paul Wigner (Hungarian: Wigner Jenő Pál, pronounced [ˈviɡnɛr ˈjɛnøː ˈpaːl]; November 17, 1902 – January 1, 1995) was a Hungarian-American theoretical physicist who also contributed to mathematical physics. He received the Nobel Prize in Physics in 1963 "for his contributions to the theory of the atomic nucleus and the elementary particles, particularly through the discovery and application of fundamental symmetry principles".

A graduate of the Technical Hochschule Berlin (now Technische Universität Berlin), Wigner worked as an assistant to Karl Weissenberg and Richard Becker at the Kaiser Wilhelm Institute in Berlin, and David Hilbert at the University of Göttingen. Wigner and Hermann Weyl were responsible for introducing group theory into physics, particularly the theory of symmetry in physics. Along the way he performed ground-breaking work in pure mathematics, in which he authored a number of mathematical theorems. In particular, Wigner's theorem is a cornerstone in the mathematical formulation of quantum mechanics. He is also known for his research into the structure of the atomic nucleus. In 1930, Princeton University recruited Wigner, along with John von Neumann, and he moved to the United States, where he obtained citizenship in 1937.
