# National Medal of Science

The National Medal of Science is the nation’s highest scientific honor. The award, established by Congress in 1959 and bestowed by the President, initially recognized outstanding contributions in the physical, biological, mathematical or engineering sciences. In 1980, Congress expanded the award to include the social and behavioral sciences.

## Robert Clayton

## Janet Davison Rowley (1925–2013)

Blum-Riese Distinguished Service Professor in Medicine, Molecular Genetics & Cell Biology and Human Genetics

**National Medal of Science for Biological Sciences, 1998**

“For revolutionizing cancer research, diagnosis, and treatment through her discovery of chromosomal translocations in cancer and her pioneering work on the relationship of prior treatment to recurring chromosome abnormalities, for epitomizing the "bench to bedside" philosophy in her application of basic discoveries to clinical medicine, and for her leadership nationally and internationally in the oncology and biomedical communities.”

## Alberto Calderón (1920–1998)

Professor in Mathematics

**National Medal of Science for Mathematics & Computer Science, 1991**

For his ground-breaking work on singular integral operators leading to their application to important problems in partial differential equations, including his proof of uniqueness in the Cauchy problem, the Atiyah-Singer index theorem, and the propagation of singularities of non-linear equations.

## Milton Friedman (1912–2006)

Paul Snowden Distinguished Service Professor in Economics; Nobel Laureate in Economic Sciences, 1982

**National Medal of Science for Behavioral & Social Science, 1989**

“For his theoretical contributions, and for application, of the principles of scientific empirical and statistical methods to the field of economics and the social sciences, and to problems critical to the Nation in general.”

## Eugene Parker

S. Chandrasekhar Distinguished Service Professor Emeritus in Physics, Astronomy & Astrophysics and the Enrico Fermi Institute

**National Medal of Science for Physical Sciences, 1989**

“For his fundamental studies of plasmas, magnetic fields, and energetic particles on all astrophysical scales; for his development of the concept of solar and stellar winds; and for his studies on the effects of magnetic fields on the solar atmosphere.”

## Saunders Mac Lane (1909–2005)

Max Mason Distinguished Service Professor Emeritus in Mathematics

**National Medal of Science for Mathematics & Computer Science, 1989**

“For revolutionizing the language and content of modern mathematics by his collaboration in the creation and development of the fields of homological algebra and category theory, for outstanding contributions to mathematics education, and for incisive leadership of the mathematical and scientific communities.”
