Frank Arthur Bellamy (17 October 1863 – 15 February 1936) was a British astronomer.
Bellamy attended Magdalen College School, Oxford and a few months before his eighteenth birthday in July 1881 was appointed Second Assistant at the Radcliffe Observatory, a post that had previously been held by his older brothers Frederick and Harry.
[4] In 1930 Frank Bellamy and his niece Edith moved to 2 Winchester Road, Oxford, and it has a blue plaque in their memory.
Despite his long partnership with his niece, he left a valuable collection to Cambridge University.
His niece's finances were helped when Cambridge University refused Bellamy's bequest so that it could be sold.
