Life and education

Born José Adem Chahín[1] in Tuxpan, Veracruz, (published his works as José Adem), Adem showed an interest in mathematics from an early age, and moved to Mexico City in 1941 to pursue a degree in engineering and mathematics. He obtained his B.S. in mathematics from the National Autonomous University of Mexico (UNAM) in 1949.[2] During this time he met Solomon Lefschetz, a famous algebraic topologist who was spending prolonged periods of time in Mexico. Lefschetz recognized Adem's mathematical talent, and sent him as a doctoral student to Princeton University where he graduated in 1952.[3] His dissertation, Iterations of the squaring operations in algebraic topology, was written under the supervision of Norman Steenrod and introduced what are now called the Adem relations.[4]

His brother is geophysicist Julián Adem, who obtained a Ph.D. in applied mathematics from Brown University in 1953.[5] Julián's son is topologist Alejandro Adem.[6]

Career

Adem became a researcher at the Mathematics Institute of UNAM (1954–1961), and then head of the Mathematics Department at the Instituto Politécnico Nacional (1961–1973).[1] He was elected to El Colegio Nacional on 4 April 1960.[2]

In 1951 he was awarded a Guggenheim Fellowship.[7] In 1956, Adem started the second series of the Boletín de la Sociedad Matemática Mexicana.[3]
