He is an American photographer born in Concord (Massachusetts) in 1952 and based in New York. Graduated magna cum laude in Art History from Boston University, his photographic work, characterized by the use of color and blending, finds in the human figure and in classical Greek and Roman art an important source of inspiration. Bill Armstrong's extensive artistic career includes works in the collections of the Philadelphia Museum of Art, Brooklyn Museum, Houston Museum of Fine Arts, Santa Barbara Museum of Art, and Getty Center in the United States, as well as in various European countries, including the Victoria & Albert Museum in London and the Bibliothèque Nationale de France. The Vatican Museums host the mural of nine photographs titled Sistine Chapel Gestures, capturing some of the most iconic figures from the monumental fresco painted by Michelangelo in the Sistine Chapel.

These photographs, along with others from his series Renaissance, Falling through history, or Figures, are part of the selection of works to illustrate the graphic image of the 2024-25 season at the Palau de la Música Catalana, portraying the theme of human fragility and strength in a very suggestive manner: the essence of heroes and anti-heroes. The blurred effect that blurs the lines and emphasizes the shadows and color overlap enhances the archetypal nature of the human being, who carries within the seed of the hero, but also of the anti-hero.
