G. Raymond Rettew and the Penicillin Breakthrough
Near Wilmington, Pennsylvania
In nineteen forty-three, an auto repair shop right here in West Chester became one of the most consequential laboratories in American history. G. Raymond Rettew, a local chemist, had cracked the problem of producing penicillin at industrial scale.
Working with Wyeth Laboratories, his converted garage became a major source of the world's first antibiotic for the Allied armed forces. The timing was critical: Allied forces were fighting on multiple fronts, and infected wounds were killing soldiers who might otherwise have survived. Rettew's mass-production method helped change that.
By D-Day in nineteen forty-four, enough penicillin existed to treat virtually every Allied casualty who needed it. The Nobel Prize for penicillin's discovery went to Fleming, Florey, and Chain, but the unglamorous work of scaling it up, done quietly in a West Chester garage, saved lives that pure science alone could not reach.
