Katherine MacLean

Katherine Anne MacLean (January 22, 1925 – September 1, 2019) was an American science fiction author best known for her short fiction of the 1950s which examined the impact of technological advances on individuals and society.
Profile.
Damon Knight wrote, "As a science fiction writer she has few peers; her work is not only technically brilliant but has a rare human warmth and richness." Brian Aldiss noted that she could "do the hard stuff magnificently," while Theodore Sturgeon observed that she "generally starts from a base of hard science, or rationalizes psi phenomena with beautifully finished logic."
According to "The Encyclopedia of Science Fiction", she "was in the vanguard of those sf writers trying to apply to the soft sciences the machinery of the hard sciences".
Her stories have been included in anthologies and a few have had radio and television adaptations. Three collections of her stories have been published.
It was while she worked as a laboratory technician in 1947 that she began writing science fiction. Strongly influenced by Ludwig von Bertalanffy's General Systems Theory, her fiction has often demonstrated foresight about scientific advances. 
She died on September 1, 2019 at the age of 94.
