I’ve caught the collector’s bug again. What is it this time? Antique astronomy tools. And I’m blaming it on the Adler Planetarium, the first in America and home to one of the world’s largest collections of historic scientific instruments. It all began when I stumbled upon their online collections, a dangerous rabbit hole for those of us who have a penchant for peculiar and otherworldly objects that would fit perfectly in a cabinet of curiosities.
The Adler Planetarium in Chicago opened its doors to the public in 1930, complete with three full sized theatres and a significant collection of antique scientific instruments dating back to the late 15th century, acquired by wealthy businessman Max Adler. He had learned of a sale of astronomical instruments and antiques by W. M. Mensing in Amsterdam, which he purchased in its entirety.
Today while the planetarium inspires exploration and understand of the universe upstairs, down below, they’re also hiding an incredible archive of the museum’s curiosities that aren’t on display. The Webster Institute for the History of Astronomy cares for Adler’s collections, and occasionally has ‘explorer days’ when they let the public come and poke around their cabinets.
I did an extensive dig through their digitised collections for those of us that can’t race over to the planetarium this very minute and demand entry to the archives.
Here’s what I found…
