Alumni Society in 1984 (now called the Berkeley Engineering Innovation Award). He was a frequent speaker in civil engineering courses and a loyal “Bears Backer” for many seasons.
After graduation, Louis went to work as a junior engineer for the state of California with the Division of San Francisco Bay Toll Crossings, further stimulating his interest in bridges. Then in 1951 he joined Tudor Engineering Company, at that time a small firm with an excellent reputation in structural design, particularly of bridges. Within 10 years he became a vice president and a member of the Board of Directors. In 1963 and for the next 20 years he served as president and chief executive officer of Tudor. He became chairman in 1983 and served in that position until his retirement in 1986.
During his career Louis managed many challenging projects. One of his favorites was the Tagus River Bridge piers in Lisbon, the deepest in the world at that time and made more difficult by the steeply sloping rock foundation. Louis was also one of a select group of visionary leaders who foresaw the need for a regional rapid transit system in the San Francisco area. This led to his proudest accomplishment, the BART System—the San Francisco Bay Area Rapid Transit System—America’s first modern transit system. In this joint venture—PBTB (Parsons Brinckerhoff-Tudor-Bechtel)—Louis was on the Joint Venture Board of Control, with overall design and construction responsibilities. Tudor had direct responsibility for the design of the entire system, aerial structure, with its difficult soil and foundation conditions and strong seismic design requirements. That aerial structure has since survived two major earthquakes in San Francisco. The PBTB Joint Venture moved on to guide the design of the Caracas Metro, with heavy emphasis on technology transfer to the local Venezuelan staff.
The final PBTB joint venture project was MARTA—the Metropolitan Atlanta Rapid Transit Authority—for which planning began in 1967 and, after many political and environmental issues, moved into construction in 1975. Louis was again on the joint venture board, with overall design and construction responsibilities, until 1976. At that time, new
