Various sites claim that Dr. Mahmoud Hessaby, a senator of the previous Iranian regime, was a student of Albert Einstein.
Hessaby was the sole Iranian student of Professor Albert Einstein
However, this has been disputed.
For example, his Wikipedia talk page:
I removed the text that Dr. Hesaby was a student of Albert Einstein. Other than a single picture and lots of hearsay, I haven't been able to find a credible source proving that he was a student of Albert Einstein.
Was Mahmoud Hessaby one of Einstein's students?
