William Bernhardt Tegetmeier
William Bernhardt Tegetmeier FZS (1816 – 19 November 1912)  was an English naturalist (with an interest in pigeons, fowl, and bees), a founder of the Savage Club, and a writer and journalist of domestic science.
Born in Colnbrook, Buckinghamshire, he was educated by his father and at University College London. Tegetmeier was already a published authority on poultry when he first met Charles Darwin: they became correspondents, and Tegetmeier eventually became a Darwinist.
Whilst living in Fortis Green, near Muswell Hill in north London, in the 1850s Tegetmeier became interested in bee keeping, and discovered how bees created the hexagon-shaped cells in their hives. He died in Hampstead and his remains rest in East Finchley Cemetery.
