Marijane Meaker (born May 27, 1927) is an Americannovelist and short storywriter in several genres using different pen names. From 1952 to 1969 she wrote twenty mystery and crime novels as Vin Packer, including ''Spring Fire'', which is credited with launching the genre of lesbian pulp fiction (although few of Packer's books address homosexuality or feature gay characters). Using her own observations of lesbians in the 1950s and 1960s, she wrote a series of nonfiction books about lesbians under the pen name Ann Aldrich from 1955 to 1972. In 1972 she switched genres and pen names once more to begin writing for young adults, and became quite successful as M.E. Kerr, producing over 20 novels and winning multiple awards including the American Library Association's lifetime award for young-adult literature, the ALA Margaret Edwards Award. She was described by ''The New York Times Book Review'' as "one of the grand masters of young adult fiction." As Mary James, she has written four books for younger children.
Regardless of genre or pen name, Meaker's books have in common complex characters that have difficult relationships and complicated problems, who rail against conformity. Meaker said of this approach, "I was a bookworm and a poetry lover. When I think of myself and what I would have liked to have found in books those many years ago, I remember being depressed by all the neatly tied-up, happy-ending stories, the abundance of winners, the themes of winning, solving, finding — when around me it didn't seem that easy. So I write with a different feeling when I write for young adults. I guess I write for myself at that age."
