Andrew Marienhoff Sessler (December 11, 1928 – April 17, 2014) was an American physicist, academic atUniversity of California, Berkeley, former director of theLawrence Berkeley National Laboratory (1973–1980), humanitarian and former president (1998) of theAmerican Physical Society.^[1]

Sessler was born inNew York City in 1928.^[2] He was educated atHarvard University (B.A. in mathematics) andColumbia University (Ph.D. in physics)^[3] with dissertationHyperfine structure of³He.^[4] From 1954 to 1959, he was a member of the faculty atOhio State University before moving to theLawrence Berkeley National Laboratory where he served as Lab Director in 1973-80.

His areas of expertise were the physics of particle accelerators, particle physics and plasma physics. In addition to accelerator physics, he also published theoretical work on quantum-theoretical statistical mechanics, atomic physics and superfluidity. Sessler was also active in the study group of theNational Academy of Sciences of the long-term effects of the atomic bombing ofHiroshima andNagasaki, and in an initiative group of APS against landmines. Sessler was a member of theAmerican Committee for Peace in Chechnya.

In 1970, he became anErnest Orlando Lawrence Award laureate. On January 13, 2014, Sessler andAllen J. Bard were awarded theEnrico Fermi Award.^[5]

Sessler lived inOakland, California.^[6] He died in 2014 after a long illness.
