I tried cleaning out one of my e-mail inboxes recently and came upon an e-mail I received MONTHS ago, which I’d read but never answered, simply because I didn’t know the answer. It was from peacay of BibliOdyssey, who asked me way back when if I knew of any resources of (old, archived) microscopic images. I just didn’t know, because if I want to find old pictures, my source is BibliOdyssey. I’m glad to see he did end up finding the things he was looking for. Here’s a recent post full of drawn biological images from the German Natural History Museum’s Christian Gottfried Ehrenberg collection. There was a time when drawing skills were required in biology, and it wasn’t even that long ago.
If you like old images (not just scientific, but of anything, really) there’s also a BibliOdyssey book now, bringing us back full circle with images from the pre-internet age now once more on paper!
