Silliman, BENJAMIN, was born in Connecticut, United States, America, in 1779, and after being educated at Yale College, and making a tour in Europe, he settled down as professor of chemistry at that institution. In 1818 he started Silliman's Journal, for many years the chief scientific periodical in America, and he delivered hundreds of popular lectures on chemistry and geology. In 1853 he retired from his professorship, and brought out an interesting record of his last visit to Europe in 1851. He was a prominent abolitionist, but died in 1864, before his views had triumphed. His son, born in 1816, succeeded him as editor and professor, wrote several useful manuals, and died in 1885.
