This sterling silver pin (or a similar one in bronze) was issued to participants in the Manhattan Project.

Certificates like this were also issued...

My father worked on the Manhattan Project, and I have both his pin and certificate. This seemed like an appropriate day to post those images.

That's amazing. Thanks for posting, I had never seen those before. And, most of all, thanks to your father and the others who toiled in secret to secure our Republic.

Amazing! Your Dad helped save countless lives. Thank you for sharing.

God bless your Dad, my Dad and all the others who prevailed in that huge, horrible war.

"Today" my Dad was on Luzon, Philippines just getting word their Operation Olympic landings on Kyushu, November 1, 1945, might be a little easier than they were previously expecting:

How interesting. Thank you for posting.

Thanks for posting. Fascinating stuff.

Your father worked on a project that saved many American lives and the lives of many Japanese as well.

Your father is among the many un-sung hero’s of WW II.

My father's first cousin, a chemist, was drafted during WWII and posted to Oak Ridge, TN. For the rest of his life, he refused to say he had worked on the A-bomb, but there was nothing else going on at Oak Ridge. After the war, he spent the rest of his career teaching biochemistry to medical students.

That is really cool! I do work over at the Hanford Facility in Eastern Washington quite a bit. (Called Richland City in the article. I told my mom that and she said “Oh - that's where Frank Johnson worked during the war - making airplane wings.”

“Um, mom - he wasn't making airplane wings - that was where they processed the uranium for the A-bombs.”

“No - he worked for Alcoa, making aluminum airplane wings.”

I'm not sure if I ever convinced her that he may have thought he was making parts for planes, but he wasn't.

The housing was off the base and in town. But the houses were all owned and managed by the government. Part of the reason was so “maintenance” workers could go in and check for burnt-out light bulbs, and then go through the house looking for any secret information or things that a worker might have brought home.

That is amazing memorabilia. Thanks for posting!
