Who was William LeMessurier?

William "Bill" James LeMessurier, Jr. was a prominent American structural engineer.

Born in Pontiac, Michigan, LeMessurier graduated with an AB from Harvard, went to Harvard Graduate School of Design and then earned a master's degree from Massachusetts Institute of Technology in 1953. He was the founder and chairman of LeMessurier Consultants. He was awarded the AIA Allied Professions Medal in 1968, elected to the National Academy of Engineering in 1978, elected an honorary member of the American Institute of Architects in 1988, and elected an honorary member of the American Society of Civil Engineers in 1989. In 2004, he was elevated to National Honor Member of Chi Epsilon, the national civil engineering honor society.

While responsible for the structural engineering on a large number of prominent buildings, including Boston City Hall, the Federal Reserve Bank of Boston, the Singapore Treasury Building and Dallas Main Center, LeMessurier is perhaps best known for a structural controversy.
