In anticipation of the upcoming Olympics in Beijing, Sheldon Breiner, a resident, a geologist and an active member of the Portola Valley community, has posted online slide shows from several visits to China in the 1970s.
In 1974, Mr. Breiner went to give talks on earthquake prediction and resource exploration, he said. In 1977, he visited with his wife Mimi as guests of the government. In 1977, he led a geophysics delegation from the United States and Canada. And in 1981, he won a special permit to travel throughout the country with his son David.
