Brown's Introduction to Organic Chemistry, Global Edition

William H. Brown is Professor Emeritus at Beloit College, where he was twice named Teacher of the Year. He received his PhD from Columbia University under the direction of Gilbert Stork and did post--doctoral work at California Institute of Technology and the University of Arizona. Twice he was Director of a Beloit College World Affairs Center seminar at the University of Glasgow, Scotland. In 1999, he retired from Beloit College to devote more time to writing and development of educational materials. Although officially retired, he continues to teach Special Topics in Organic Synthesis on a Yearly basis.
