Frederick Childe Hassam (b. October 17, 1859, Dorchester, Boston, Massachusetts – d. August 27, 1935, East Hampton, New York) was a prominent and prolific American Impressionist painter, noted for his urban and coastal scenes.

Along with Mary Cassatt and John Henry Twachtman, Hassam was instrumental in promulgating Impressionism to American collectors, dealers, and the museums. He produced over 3,000 paintings, watercolors, etchings, and lithographs in his career, and was a founding member of The Ten, an influential group of American artists of the early 20th century. His most famous works are the “Flag” paintings, completed during World War I.

[I saw an example of Frederick’s work in the art group on Gab. I’d never heard of him before, of course. The piece used there was the church immediately below. It really caught my eye as to me few things are as beautiful as that mixture of blue, gold, white and green. I would have loved to have seen the sky more blue in the beach scene below it. The next is just a masterpiece of snowy Boston with evening setting in, with that golden light. Next to last is one in his ‘flag’ series. I would have loved to see just a touch more detail of the people and the street scene. I understand his flag series was his most popular, painted during WW I.]
