#photo archives
Hello my Tumblr science nerd friends.
After almost 3 years of running the Photo Archives Tumblr, it is time for me to say goodbye.
Thank you so much for joining me in this photo archives worm hole.
The Tumblr will go on a small hiatus, but will be back in full force soon.

Shown here is a general view of acetylene welding at the U.S. Department of Agriculture’s Fixed Nitrogen Research Laboratory located in Washington, D.C. The man visible in the photograph is identified as J.J. Connor. This photograph is believed to have been taken in the electrical shop located at the Laboratory.
