Albert Einstein passed away #OTD in 1955. The cause was complications from a ruptured abdominal aneurysm.

Doctors recommended surgical intervention but Einstein declined. He told them: “I have done my share; it is time to go. I will do it elegantly."

Here is his office as he left it.

Besides the famous chalkboard photo, Ralph Morse also took a close-up of Einstein's desk.

Covered with papers, his pipe laying on its side, a photo set down as if he’d just been looking at it. It is a very relatable desk.
