Born in Milwaukee on Sept. 10, 1931 to William Martin Metzker and Mary Helen Metzker (nee Kreuger). Metzker grew up with a brother, Carl and a sister Mary Ellen. With his parents focused on his sister's cerebral palsy, Metzker developed a sense of isolation; he considered himself "acutely shy". Metzker loved classical music, history and drawing, but his passion for photography was cemented when his mother gave him a camera at age 12. Photography "gave him a connection, a way of formally encountering the world and expressing his love for it, or what he calls his belief “about the goodness of things." Metzker would develop photographs in his bedrooom, winning numerous high school competitions sponsored by Eastman Kodak.
After graduate studies at the Institute of Design in Chicago, Metzker travelled extensively throughout Europe in 1960-61, where he had two epiphanies: that "light" would be his primary subject, and that he would seek synthesis and complexity over simplicity. Metzker often said the artist begins his explorations by embracing what he doesn't know.
