This year marks the 60th anniversary of the first class of OSA Fellows. At its April 1959 meeting, the OSA Board of Directors elevated 115 of its members to the rank of Fellow — a first for the Society. Today we continue that tradition as we congratulate the 2019 OSA Fellows. These members come from 20 different countries, with more than half from outside the United States. They are recognized for their distinguished contributions to education, research, engineering, business and society.
