A cousin of
Ralph Waldo Emerson, William was born in
Alton, Illinois, and trained in the office of Jonathan Preston (1801–1888), an architect–builder in
Boston. He formed an architectural partnership with Preston (1857–1861), practiced alone for two years, then partnered with
Carl Fehmer (1864–1873). He is best known for his
Shingle Style houses and inns, many of them in
Bar Harbor, Maine. He worked with fellow Boston designer
Frederick Law Olmsted on the creation of the
National Zoo in Washington, D.C., designing several of the zoo's first buildings. Emerson was a friend of the Boston painter
William Morris Hunt, who painted a portrait of Emerson's son Ralph, shown at an exhibition of Hunt's work at the
Boston Museum of Fine Arts in 1880. Emerson died in
Milton, Massachusetts. == Personal life ==
