Richard Hawley Tucker was born in 1859 in Wiscasset, Maine of a family of ship owners and seafarers. At age 14 he went to sea and at age 15 entered Lehigh and graduated from Lehigh in 1879 in civil engineering. As a student he was inspired to an interest in astronomy by Professor Charles L. Doolittle (professor of mathematics and astronomy 1875-1895). During his student years he appeared to be fond of music with many notations made about musical productions he attended especially in Bethlehem and Philadelphia. Upon graduation he went to work for Prof. Lewis Boss at Dudley Observatory, Albany, New York (now Schenectady, N.Y.) for four years and briefly worked at the U. S. Coast & Geodetic Survey. In 1883 he returned to Lehigh as an instructor of mathematics and astronomy but left in 1884 when he was offered a position by Dr. Benjamin A. Gould, Jr. with the Argentine National Observatory as an assistant in surveying the stars in the southern sky. Dr. Gould also recruited Miles Rock, LU 1869 to work in Argentina. In 1893 he was offered a position at the Lick Observatory in California operating the Meridian Circle program to make precise measurements of star positions. In 1908 he lead an expedition sponsored by the Carnegie Institute in Washington, D.C. to San Luis, Argentina to make accurate measurements of the position of the stars in the southern sky during which he personally made 20,800 observations of stars out of the 89,000 made on the expedition. After this Argentine trip he returned to Lick Observatory and remained there until his retirement in 1926 becoming Emeritus Astronomer. He is remembered by Lick Observatory as being a methodical, persistent investigator. In 1914 he married Ruth Standen, a secretary at Lick and they had two daughters. He received an honorary Ph.D. from Lehigh in 1922. Tucker died in Palo Alto in 1952. He enjoyed sports – hunting, fishing, hiking, golfing and tennis. He was a member of the American Association for Advancement of Science, American Seismological Society, American Philosophical Society, Astronomical Society of Pacific, Astronomische Gesellschaft and Société Astronomique de France. Crater Tucker on the Moon is named for him.
