Passage: Watson graduated in 1943 with BS in electrical engineering from Iowa State College. From 1943 to 1946 he was a researcher at the United States Naval Research Laboratory in Washington, D.C. During his work for the U.S. Navy he went to night school at George Washington University. He graduated from the University of Iowa with Ph.D. in 1948 with thesis The polarizability of the meson-charge cloud of a neutron in an external electrostatic field. He was from 1948 to 1949 an Atomic Energy Commission (AEC) Fellow at the Institute for Advanced Study and from 1949 to 1951 an AEC Fellow at the Berkeley Radiation Laboratory. He was from 1951 to 1954 an assistant professor of physics at Indiana University and from 1954 to 1957 an associate professor of physics at the University of Wisconsin, Madison. In 1953 he was elected a fellow of the American Physical Society. From 1957 to 1981 he was a staff member of Lawrence Berkeley National Laboratory, as well as a professor of physics at the University of California, Berkeley. In 1974 he was elected a member of the National Academy of Sciences. From 1981 to 1991 he was the director of the Marine Physical Laboratory, Scripps Institute of Oceanography, as well as a professor of physical oceanography at the University of California, San Diego. In 1991 he retired as professor emeritus. His doctoral students include Shang-keng Ma.

question:
Passage: During the reign of King Edward the Confessor a lady called Elviva (probably a Latin rendering of the Old English name lfgifu), held the manor of Ambrosden. The Domesday Book records that by 1086 she had been replaced by Hugh d'Ivry, butler of William the Conqueror and brother of Roger d'Ivry, who owned several manors in Oxfordshire. Hugh's nephew Roger II d'Ivry inherited Ambrosden and by 1194 it was part of the Honour of St. Valery. Ambrosden thus passed to Edmund, 2nd Earl of Cornwall, who in 1288 gave the manor to Ashridge Priory of the Augustinian order of the Brothers of Penitence. Ashridge Priory retained Ambrosden until the priory was dissolved in 1539 in the Dissolution of the Monasteries.

Passage: His grandfather and father Holmes Rolston, and Holmes Rolston Jr (who did not use the Jr) were Presbyterian ministers. Rolston III was married on June 1, 1956 to Jane Irving Wilson, with whom he has a daughter and son. He holds a B.S. in physics and mathematics from Davidson College (1953) and a Bachelor of Divinity degree from Union Presbyterian Seminary (1956). He was ordained to the ministry of the Presbyterian Church (USA) also in 1956. He received a Ph.D. from the University of Edinburgh in 1958; his advisor was Thomas F. Torrance. He earned an M.A. in the philosophy of science from the University of Pittsburgh in 1968, beginning his career later that year as an assistant professor of philosophy at Colorado State University and becoming a full professor in 1976. He became a University Distinguished Professor in 1992. He gave the Gifford Lectures, University of Edinburgh, 1998-1999. He was named Templeton Prize laureate in 2003. He has lectured by invitation on all seven continents. Colorado State University inaugurated the Holmes Rolston Endowed Chair in Environmental Ethics in October 2016; for the inaugural lecture by Kenneth Shockley, click here..
