Professor Ralph S. "Roney" Williams '35 died May 4, 1998, in Boothbay Harbor, Maine, after nearly seven decades of devotion and service to Colby as student, teacher, administrator and trustee. He was 85.     Williams returned to the College in 1947 after earning a master's degree in business administration at New York University, serving as a lieutenant commander in the Navy during World War II and teaching for a year at Boothbay Harbor High School.     In the first years he was an instructor in business administration, administrative assistant to President J. Seelye Bixler, director of Roberts Union and director of adult education and summer programs. In 1959 he was appointed administrative vice president of the College, and in 1960 he became secretary of the corporation and Herbert Wadsworth Professor of Administrative Science. On his retirement in 1973, following a semester as acting president of the College while President Robert E.L. Strider was on leave, he was awarded the degree of doctor of humane letters.     Williams continued his support of Colby through alumni activities, committee appointments and financial contributions and as a member of the Board of Trustees, where he helped guide Colby's investments and build the College's fiscal strength. In 1972 he received a Colby Brick for his loyalty and dedication to the College, and in 1985 the former Kappa Delta Rho fraternity house was renamed in his honor.     Born in New York City, where he attended public schools, he became a trustee of eight Maine corporations and was elected to various boards throughout his lifetime, including the Maine State Criminal Justice Academy, YMCA and Good Will-Hinckley School, where he had prepared to enter the College. Sixty years later he established a scholarship fund at Colby for Good Will students.     His wife of 47 years, Barbara Howard Williams, died previously. He is survived by his second wife, Barbara Nowack Williams, his daughters, Marinel and Jane, seven grandchildren, including Susan Carbone '90 and Robert Carbone '93, and two great-grandchildren.
