Marilyn Brooke Goffstein, award-winning author-illustrator and fine artist, whose work was published under the name M.B. Goffstein and Brooke Goffstein, died on December 20, 2017—her 77th birthday—following a long illness.
Goffstein was born on December 20, 1940 in St. Paul, Minn. and grew up there. In her autobiographical essay for Fourth Book of Junior Authors and Illustrators, she said that she knew from childhood that she would pursue art as a profession. That feeling, she said, stemmed from her Minnesota roots where her parents’ examples helped instill in her the idea “that work was the only real dignity, the only real happiness, and that people were nothing if their lives were not dedicated. My choice was art.”
During her years at Bennington College she studied writing, poetry, and art. It was during this time that she began experimenting with woodcarving and also with small pen-and-ink drawings, which eventually became her signature picture-book illustration style. Goffstein earned her B.A. in 1962 and by then her paintings and drawings had been featured in one-woman shows in St. Paul and New York City, and she had completed two internships at two New York City printers.
After graduating from college, Goffstein moved to New York City and pursued illustration work while working part-time as a bookseller. Though she received positive feedback on her artwork from book editors, she did not land a project until she tried pitching a project that she both wrote and illustrated. In 1996, her first picture book, The Gats!, was published by Michael di Capua at Pantheon. Goffstein’s husband, David Allender, editorial director at Scholastic Book Clubs, recalled the story of that breakthrough. “Brooke was first published in 1966 because Maurice Sendak came to a gallery show of her work,” he said. “Maurice brought his friend, Michael di Capua. Michael offered to publish her first book, The Gats! at Pantheon. And Brooke took him up on the offer. Later that year, Michael took her with him to Farrar, Straus and Giroux.”
Thus began a very prolific period that saw Goffstein often producing more than one book per year...
