Long before Facebook, Sheila Metzner, 75, began creating vast crisscrossing networks of friends, coworkers who turn into friends, and family members. With a big personality and a penchant for travel, she has built a global network fortified by wide-ranging assignments that keep her on the move. "It's amazing how many lines cross through one another—and they increase as you get older," says Metzner, who met Ralph Lauren after writing him a fan letter and has been shooting his ad campaigns on and off for decades. "Photography is my whole life. It has been part of my personal search. I met Warren Beatty after I told an interviewer from the Daily News that I wanted to photograph him. I got to meet David Lynch during a story for House & Garden. I told him that I'd love to work on one of his movies and he invited me to the set of Wild at Heart. I just wrote a letter to [artist] James Turrell. He bought a volcanic crater and did the interior of it." Clearly Metzner wants an invite—and if her track record is any indication, she'll probably get one.
