“Selling Science in the 20th Century” was a public talk delivered as part of the Chemical Heritage Foundation’s Saturday Speakers series. The presentation focused on Beckman Instruments, science advertising, the Beckman Historical Collection, and the digitization component of CHF’s Beckman Legacy Project. Audience members also had the opportunity to examine materials from the archive and the museum’s handling collection. (These slides represent the second half of the talk; the first half was devised and delivered by Sarah Newhouse on the same date.)
