DALLAS, TX.- Heritage Auctions’ April 6 Photographs Auction will feature the largest group of Ruth Bernhard photographs ever to appear at auction.

Born in Berlin in 1905, Bernhard moved to New York City in 1927, where she became a photographer. In the late 1920s, she became friends with photographer Berenice Abbott and her partner, critic Elizabeth McCausland. A few years later, she started photographing women in the nude, the art form for which she eventually would become best known. Shortly after she met photographer Edward Weston in 1935, she moved to California, where he lived, before moving back to New York four years later. After eight years she moved back to California, where she remained for the rest of her life, finally settling in San Francisco where she befriended photographers Ansel Adams, Imogen Cunningham, Minor White and Wynn Bullock.

“This is the most substantial offering of Ruth Bernard photographs ever to appear for sale,” Heritage Auctions Rare Photographs Director Nigel Russell said. “This is a unique opportunity for those who have admired her timeless female nudes or thoughtful still lifes.”

Comprising 71 lots of her elegant female nude studies and sublime still-lifes, the auction offers four complete portfolios, including The Eternal Body, 1993 ($10,000-15,000).
