H. Bolton Seed, a scientist known internationally for his understanding of soil behavior during earthquakes and for sharing that expertise with much of the world, has died of cancer at his home in Orinda, Calif.
The professor of civil engineering at UC Berkeley was 66 when he died Sunday.
"Harry was a giant among civil engineers in the world, that's the only way you can regard Harry Seed," Karl S. Pister, dean of the Berkeley College of Engineering, said in a statement released through the university.
In 1987, Seed, a native of England who became a U.S. citizen, received the National Medal of Science, considered the nation's highest scientific honor. During his career, he received more than 40 international and national awards.
Seed made major research contributions in the fields of structural engineering design, highway engineering, geotechnical engineering and earthquake engineering.
He was part of an international team called in to study the Aswan Dam in Egypt after earthquakes posed questions over its seismic strength. He also served as consultant to the Tarbela Dam in Pakistan, the Oroville Dam in California and the Alaska Pipe-Line Project.
