"We had quite an interesting lecture last week by Prof. [Benjamin] Silliman [Jr.] of Yale. His subject was the Yosemite valley. He gave us a great many representations of the scenery, upon canvas, by the aid of the magic lantern..." From a letter written by a member of the Class of 1872
The chemist and geologist, Benjamin Silliman Jr., followed in his distinguished father’s footsteps, becoming both a chemistry professor at Yale and assisting with The American Journal of Science and the Arts, the preeminent American scientific journal, known generally as “Silliman’s Journal.” Silliman Jr. was active in the development of petroleum fields in Pennsylvania and later in California. A decade after this visit to the college, he and his partner James Farnsworth were the architects of the Vassar Brothers Laboratory at the college.
