Josephine Arader

Josephine Arader

Director of Arader Galleries, California.

Josephine is passionate about the tradition of Natural Historians throughout European and American History. She believes that there is a strong correlation between the Natural Historians of the past and our current understanding of and relationship with the Natural World. The watercolors, color plate books and cartographic works that were produced by natural historians from the 16th-19th Centuries can give us a poignant understanding of the times from which they originate as they bring the past into the present with vivid power.

Josephine sits on the board of The Natural History Institute, which provides leadership and resources for a revitalized practice of natural history that integrates art, science, and humanities to promote the health and well-being of humans and the rest of the natural world.

She has acted as the Treasurer of the Antiques Dealers Association of California and is regularly called on to vet works on paper at Antique Shows and has served as a judge for botanical art shows. Her clients are a mix of private individuals and foundations.
