Richardson returned from Europe for good in 1900. In 1902 he and his wife Frances hired Ralph Adams Cram to design their home high atop Windmill Hill in Ipswich Massachusetts. Ipswich provided Richardson an array of coastal and pastoral inspirations. He continued to paint portraits, primarily on commission, but concentrated on the nearby marshes, upland fields, and ocean.
He continued to use various media including pastels, water color, but most often oil.
By 1903 Arthur Wesley Dow (an Ipswich native), Henry Rodman Kenyon, John Worthington Mansfield, and Theodore Wendel were all in Ipswich and are known today as the Ipswich Painters. Richardson and Kenyon often shared similar subjects.
For many years, he also maintained a studio in Boston. In summer he often relocated to another area of New England, from Lyme, Connecticut, to the Isles of Shoals, N.H. and Boothbay Harbor in Maine. His exhibitions included the St. Louis World’s Fair, the Philadelphia Art Society, the Boston Art Club, the Exposition of Independents in New York, the American Water Color Society, the Salamagundi Club and locally at various venues on the North Shore.
Richardson died suddenly at home in 1934.
