Retired Houghton Mifflin garden book editor Frances Tenenbaum of Cambridge and Martha's Vineyard was honored at The Horticultural Society of New York's annual black tie Dinner Dance in New York City Tuesday. Also honored at the 109-year event were Stephen Orr, gardening editorial director for Martha Stewart Living Magazine, architects and interior designer David Easton and writer-director Alex Timbers. Accepting the award for Tenenbaum were her daughter, Jane Tenenbaum, a book designer in Cambridge, and author Phyllis Meras of Martha's Vineyard. During her long career, Frances Tenenbaum edited dozens of titles, including books on Tasha Tudor, republished classics such as Celia Thaxter's "An Island Garden" which Houghton had first published 100 years before. She also wrote a dozen books and edited the dreary Taylor's Encyclopedia of Gardening into a best selling reference series. "We are honoring Frances for her remarkable contrition as an author and lifelong gardener. The books she edited as well as wrote fill the Society's library," said executive director Sara Hobel. "Before Frances, the only garden writers known in America were British."
