Louis de Branges de Bourcia (born August 21, 1932) is a French-American mathematician. He was the Edward C. Elliott Distinguished Professor of Mathematics at Purdue University in West Lafayette, Indiana, retiring in 2023. He is best known for proving the long-standing Bieberbach conjecture in 1984, now called de Branges's theorem. He claims to have proved several important conjectures in mathematics, including the generalized Riemann hypothesis.
Born to American parents who lived in Paris, de Branges moved to the US in 1941 with his mother and sisters. His native language is French. He did his undergraduate studies at the Massachusetts Institute of Technology (1949–53), and received a PhD in mathematics from Cornell University (1953–57). His advisors were Wolfgang Fuchs and then-future Purdue colleague Harry Pollard. He spent two years (1959–60) at the Institute for Advanced Study and another two (1961–62) at the Courant Institute of Mathematical Sciences. He was appointed to Purdue in 1962.
An analyst, de Branges has made incursions into real, functional, complex, harmonic (Fourier) and Diophantine analyses. As far as particular techniques and approaches are concerned, he is an expert in spectral and operator theories.

A native of Terre Haute, Indiana, Stuart E. Dreyfus is professor emeritus at University of California, Berkeley in the Industrial Engineering and Operations Research Department. While at the Rand Corporation he was a programmer of the JOHNNIAC computer. While at Rand he coauthored Applied Dynamic Programming with Richard Bellman. Following that work, he was encouraged to pursue a Ph.D. which he completed in applied mathematics at Harvard University in 1964, on the calculus of variations. In 1962, Dreyfus simplified the Dynamic Programming-based derivation of backpropagation (due to Henry J. Kelley and Arthur E. Bryson) using only the chain rule. He also coauthored Mind Over Machine with his brother Hubert Dreyfus in 1986.

Alice Turner Schafer (June 18, 1915 – September 27, 2009) was an American mathematician. She was one of the founding members of the Association for Women in Mathematics in 1971.

Ronald George Douglas (December 10, 1938 – February 27, 2018) was an American mathematician, best known for his work on operator theory and operator algebras.

James Newton Morgan (March 1, 1918 – January 8, 2018) was an American economist.
Morgan was born near Corydon, Indiana, on March 1, 1918. He obtained a bachelor's degree in economics from Northwestern University in 1939. He then worked for the North Appalachian Experimental Watershed of the Soil Conservation Service before returning to school, receiving a master's and doctoral degree in economics from Harvard University. Upon completing his doctorate, Morgan was named an assistant professor at Brown University. In 1949, Morgan began post doctoral work at the University of Michigan. He became an associate professor in 1953, and was named a full professor five years later. Morgan developed SEARCH, a data analysis program, during the 1960s, and became the first director of the Panel Study of Income Dynamics in 1968. Over the course of his career, Morgan was named a member of the National Academy of Sciences, and fellow of the American Statistical Association, Gerontological Society of America, and American Academy of Arts and Sciences. He retired in December 1987, and died on January 8, 2018, at the University of Michigan Hospital.

Margaret Kampschaefer Butler (March 27, 1924 – March 8, 2013) was a mathematician who participated in creating and updating computer software. During the early 1950s, Butler contributed to the development of early computers. Butler was the first female fellow at the American Nuclear Society and director of the National Energy Software Center at Argonne. Butler held leadership positions within multiple scientific organizations and women's groups. She was the creator and director of the National Energy Software Center. Here, Butler operated an exchange for the editing of computer programs in regards to nuclear power and developed early principles for computer technology.

Alice Jeanne LaDuke (born June 27, 1938) is an American mathematician who specialized in mathematical analysis and the history of mathematics. She was also a child actress who appeared in one film (The Green Promise).

Pierre Lelong (14 March 1912 Paris – 12 October 2011) was a French mathematician who introduced the Poincaré–Lelong equation, the Lelong number and the concept of plurisubharmonic functions.

John Charles Chenoweth McKinsey (30 April 1908 – 26 October 1953), usually cited as J. C. C. McKinsey, was an American mathematician known for his work on game theory and mathematical logic, particularly, modal logic.
