90481 Wollstonecraft           Discovered 2004 Feb. 16 by J. Dellinger and D. Wells at Needville.
Mary Wollstonecraft (1759-1797) was a revolutionary champion of gender equality. Arguing that the rights of women, as those of men, rely on intellectual, economic and legal autonomy, she challenged the mores of her time and influenced feminist thought for centuries.
