We cannot be certain this entertaining anecdote is 100% true, but he was a genuinely great mathematician, who in many ways was centuries ahead of his contemporaries.

He was educated at Alexandria, Egypt – famed for its knowledge and learning.

He then returned to Syracuse where he became famed as both a mathematician, inventor, astronomer and philosopher.

He continued to correspond with mathematicians back in Alexandria, and even during his lifetime, he gained a strong reputation for being a mathematical genius.

He wrote several treatises and corresponded with other mathematicians of the day.

He had a brilliant mind and made many important developments in the subject.

While he lived in the White House he kept a number of pet cats, most famously Dixie and Tabby.

He has also given more focus on environmental issues.

In 1921, he was awarded the Nobel Prize in Physics for his contributions to theoretical physics and the evolution of Quantum Theory.

At college, he met a fellow student Mileva Maric, and after a long friendship, they married in 1903;
