***Blanchard learned the trade of the silversmith from his father, George Porter Blanchard in Gardner, Massachusetts. In 1923, Blanchard moved to Burbank, California, where he established a studio for silversmithing. Between the 1930s and 1950, he operated a shop in Hollywood. He then worked from his home in Pacoima from the 1940s until his death in 1973.
His daughter Alice Blanchard married Lewis Wise, who conducted business as Porter Blanchard Silversmiths in Calabasas, California. After 1955, all Porter Blanchard flatware was made at the Calabasas shop, while the holloware was made at Blanchard's Pacoima home. His daughter Rebecca married Allan Adler, who continued designing as a silversmith in the Arts and Crafts tradition.
Blanchard was a member of the Boston Society of Arts and Crafts and was awarded their title of medalist in 1944.
