Background
She was the daughter of the painter Matthias Withoos. Alida Withoos was born in Amersfoort. With three brothers Johannes, Pieter, Frans, and her sister Maria, she was trained by her father in painting still lifes and botanical illustrations.
Career
Because of the invasion of Utrecht by the French, the family moved to Hoorn in 1672. In 1701, Alida married the Fijnschilder Andries Cornelisz van Dalen, a typical example of relations between artistic and painterly families in seventeenth and eighteenth century Holland. In Hoorn a number of the Withoos children were active as artists of flowers, birds, butterflies and insects.
In inventories, such images were regularly called "Withoosjes".
She painted in 1687 (at Agnes Block"s) the first pineapple bred in Europe, though these images have unfortunately not survived. Thirteen water colours that Alida made in 1694 for the coloured Moninckx Atlas, along with 425 images of plants in the Hortus Botanicus (where plants brought back in the ships of the Dutch East India Company were grown in neat rows as at Block"s house), have survived.
The Library of Wageningen University own a book of drawings bought by the collector Simon Schijnvoet that includes 7 by Alida Withoos, perhaps made for Block. These give a good idea of the high quality of her work.
She was buried in the Western Church in Amsterdam.
