I recently wrote a short post for the Pasteur Foundation about this beautiful microscope set, which Dr. Bert Hansen (his website here) found on EBay and then donated to the Chemical Heritage Foundation. (Here’s a post I wrote in October 2010 about the chemistry sets I saw during my time at the CHF.) The post, which is part of the Pasteur Foundation’s series of short pieces on Pasteur “remembrances,” also talks a bit about other Pasteur appearances in kid culture at that time. Here’s the link.
