In the late forties, engineers, Hardy Trolander and John Benedict, and chemist David Jones wanted to solve problems through what they called good science. That led them to form Yellow Springs Instruments – or YSI in 1948. Trolander was appointed the company’s first President, and along with fellow Antioch alumn, David Case, YSI continued its mission of using good science until the company was sold in 2011. Hardy Trolander died on Friday, October 11th, and to find out more about the man and his legacy, I spoke with Malte vonMatthiessen, who became president of YSI in 1983 after Trolander’s retirement. We began by talking about the ‘good science’ that Trolander believed in.
