Martha "Ricky" Richardson Weiser was the only child born to Seth and Nina Richardson. The family moved to the Washington D.C. area, where Seth was in private and federal service as an attorney. He was friends with Joe Kennedy, and obtained the first commercial rights to fly to Japan for Northwest Airlines. President Hoover appointed Richardson assistant attorney general of the United States.

Weiser was known as either Rick or Richardson in college and during her friendship with Theodore Sturgeon. In later life, she was uniformly known as Ricky. She attended Wellesley and Yale, and obtained a degree in theater direction at the latter, being the first woman to do so. Weiser married C.B. Weiser in 1950 and had two sons, Seth and Christopher.

Weiser spent most of her life in Boulder, Colorado, and was involved with the Colorado Shakespeare Festival, Boulder civics, and the Society for Creative Anachronism, Inc. (in the capacity of a Shakespearean bard).

It is unknown as to how or when Weiser met Theodore Sturgeon, but the two maintained a correspondence for some years. According to Weiser, the two were engaged for a brief period. In 1985, Sturgeon called her from his death bed, which she mentions in letters to Tandy Sturgeon and Jayne Engelhart Tannehill, Sturgeon's partner at the time of his death.

Weiser died in 2002.
