Armstrong was born in 1954, in Arlington, Massachusetts, one of four sons of Robert and Irma Armstrong.^[3] He graduated from the Satya Community School, an alternative high school in Lincoln, Massachusetts, where he met Nan Goldin at the age of 14.^[4] David openly identified as gay.^[5] On October 26, 2014, at the age of 60, he died in Los Angeles, California due to liver cancer.^[3]

Armstrong entered into the School of the Museum of Fine Arts in Boston as a painting major, but soon switched to photography after studying alongside Goldin, with whom he shared an apartment.^[3] He attended the School of the Museum of Fine Arts and Cooper Union from 1974 to 1978, and he earned a B.F.A from Tufts University in 1988 and Judy Ann Goldman Fine Art in Boston.^[6]

During the late 1970s, Armstrong became associated with the "Boston School" of photography, which included artists such as Nan Goldin, Mark Morrisroe and Jack Pierson.^[4] Their aesthetic was based on intimate snapshot portraits in saturated color.^[4]

Armstrong first received critical attention for his intimate portraits of men, either lovers or friends, in sharp focus.^[7] In the nineties, he began to photograph cityscapes and landscapes in soft focus to contrast with the resolution of his portraits. Street lights, electric signs and cars are reduced to a sensual mottled blur, complementing the vividness and tactility of his portraits.^[6]

In 1981, Armstrong created a series of black-and-white portraits which he showed at PS1's New York/New Wave exhibition. In 1996, Elisabeth Sussman, curator of photographs at the Whitney Museum, enlisted Armstrong's help in composing Goldin's first retrospective. She gained such respect for Armstrong’s eye, she acquired a few of his pieces for the Whitney permanent collection and he was subsequently featured in the Whitney 1994 biennial.^[8]

Armstrong’s work has also appeared in publications such as Vogue Paris, L'Uomo Vogue, Arena Homme +, GQ, Self Service, Another Man and Japanese Vogue and he has worked on the advertising campaigns of companies such as Zegna, René Lezard, Kenneth Cole, Burberry, Puma, and Barbara Bui.^[6] He once shot editorials for Wonderland, Vogue Hommes and Purple.^[8]

Although his primary subjects include portraits of young boys and men, Armstrong also released a book of land and cityscapes in 2002, entitled All Day, Every Day.^[4]
