Bror Julius Olsson (B.J.O.) Nordfeldt was born Tulstorg, Scania, Sweden on April 13, 1878 and his family immigrated to the US in 1892. Nordfeldt attended the School of the Art Institute and studied with Albert Herter, as well as at the Académie Julian in Paris, for a few weeks.  He learned block carving and printing from Frank Morley Fletcher in England at the Reading University College. Nordfeldt’s attention drifted from block printing after 1907. As he concentrated on his painting he was able to make a modest living selling his etchings. He did a number of lithographs for the P.W.P.A. in the 1930's, during the Great Depression.

After serving as a ship camouflager during World War I the Nordfeldts moved to Santa Fe, New Mexico in 1919 where he lived for nearly 2 decades, with trips to teach in various art schools around the country.  In 1937 he moved to Lambertville, NJ which became his permanent home. Norfeldt was an early member of the Provincetown Printers art colony in Massachusetts. In 1921, Nordfeldt was elected an associate member of the Taos Society of Artists.

Nordfeldt is often credited with the introduction of the white-line or one block relief printing method to the Provincetown artists in 1914. B.J.O. Nordfeldt died in Henderson, Texas on April 21, 1955.
