Biography:

Johannes Gerard Keulemans (1842-1912)

Keulemans was a Dutch bird artist and illustrator.

He was born in Rotterdam and as a young man he collected animal specimens for museums such as the Natural History Museum in Leiden, whose director, Hermann Schlegel, encouraged Keulemans and sent him on the 1864 expedition to West Africa. In 1869, he was persuaded by Richard Bowdler Sharpe to illustrate his Monograph of the Alcedinidae, or Family of Kingfishers (1868-1871) and to move to England, where he lived for the rest of his life.
