Vivian Hewitt

Vivian Vaughan Davies Hewitt (1888–1965) was a pioneering Welsh aviator. Born in Grimsby, Nevertheless, the view was expressed at the time that Hewitt's flight was "a more difficult and dangerous feat" than Corbett Wilson's.

Hewitt was also a keen ornithologist and set up a bird sanctuary at his home of Bryn Aber at Cemlyn Bay, Anglesey, which is now managed by The North Wales Wildlife Trust. He was known as the "world’s greatest private Great Auk collector", as he built up a collection of the skins and eggs of these extinct birds. Hewitt was also believed to have owned some or all of the Metland Egg, when he bought F. G. Lupton's egg collection in the early 1940s, although the location of the eggs is unknown after that. Hewitt's specimens are now in museums in Cardiff, Birmingham, Los Angeles, and Cincinnati.
