The only way to know about famous peronalities from the past is books and pictures. At times, a single photograph is enough to tell us about the people that make it.

Vintage photos are always interesting and more when we see unrelated famous people meeting each other. Here's a list of such meetings that we didn't realise once happened.

The two met at Einstein's house in Caputh, Berlin on 14th July 1930 when Rabindranath Tagore visited him. It is believed that they had one of the most stimulating, intellectually riveting conversations in history, exploring the age-old friction between science and religion.
