Ted Yates Johnston of Atherton died on Jan. 12, after a long battle with lymphoma. He was 79.
Mr. Johnston, a fourth-generation Californian, was born in Paso Robles in 1930 to Theodore and Josephine Johnston. He lived the majority of his life on the Peninsula and graduated from Sequoia High School in 1947.
In 1950, he graduated from the California Maritime Academy in Vallejo, and then served as a deck officer in the merchant marine and the U.S. Navy from 1950 through 1960. In 1960 he joined IBM as a computer salesman and programmer and moved to Sacramento, where he married Margaret in 1961.
Moving back to the Peninsula in 1969, he joined the computer center at the SLAC National Accelerator Laboratory on the Stanford University campus.
After he retired in 1992, Mr. Johnston biked and hiked many of the Bay Area's roads and trails, as well as several regions in France with the British Ramblers' hiking club. The trips gave him regular opportunities to butcher the French language to the bewilderment of numerous French waiters, family members said.
Mr. Johnston was an avid reader and oenophile, and he and his wife square-danced and traveled regularly. He worked as a docent at the Computer History Museum in Mountain View.
Mr. Johnston is survived by his wife of 49 years, Margaret Johnston of Atherton; and daughter Pamela Johnston of Pasadena. Memorial donations may be made to a charity of the donor's choosing.
