Albert Einstein was not a mathematician, he was a physicist. Isaac Newton was before the distinction between physicists and mathematicians was so sharp. But I don't know why you say they were "self taught". Albert Einstein was educated at the college at Aarau, Switzerland and the Federal Polytechnic School in Zurich, Switzerland where he got his Ph.D. in 1905. Newton was educated at Cambridge University, Trinity College. Leonardo Pisano Bigollo was educated at a school (not technically a "college" or "university"- this was before the start of what we would call "colleges" and "universities") in Cairo, Egypt.
