Travelling to the American West five times during the 1830s, Catlin was the first white man to depict Plains Indians in their native territory. The "New England Reformers" was a lecture by Ralph Waldo Emerson read before "The Society" in Amory Hall, on Sunday, March 3, 1844.  "The Society" has been identified as the American Anti-Slavery Society, led by William Lloyd Garrison. Lloyd Sexton Jr. (1912–1990), who is also known as Leo Lloyd Sexton Jr. was an American painter born in Hilo, Hawaii on March 24, 1912.  In 1931 he entered the School of the Museum of Fine Arts, Boston.  In 1933 he had a show of flower paintings at the Vose Galleries in Boston, followed by exhibitions at the Honolulu Museum of Art and at Gump's in San Francisco.  He spent several years in Europe, painting and traveling during the summers and studying at the Slade School of Art in London during the winters.  In his third and final year of instruction there, one of his figure paintings won first prize, and in 1936 a flower painting was exhibited the Royal Academy in London.  Sexton returned to Hilo in 1937 and concentrated on figure painting and portraiture.  That same year his painting "Nanea" was accepted and exhibited at the Royal Academy.  Sexton executed a large number of portraits and, beginning in 1934, before he left for Europe, did two commissions for the Hawaiian Pineapple Company.  He was a frequent and popular exhibitor in group shows in Honolulu.  He also had one-person shows at Honolulu's Grossman-Moody Gallery in 1957 and at the Hilton Hawaiian Village Hotel Gallery in 1961.  A retrospective of his work was held at the Contemporary Arts Center, Honolulu Advertiser Gallery, in 1966.

Kahlil Gibran (`ka-lil jə-ˈbrän) (November 29, 1922 – April 13, 2008), sometimes known as "Kahlil George Gibran" (note the artist’s preferred Americanized spelling of his first name), was a Lebanese American painter and sculptor from Boston, Massachusetts.  A student of the painter Karl Zerbe at the School of the Museum of Fine Arts, Boston, Gibran first received acclaim as a magic realist painter in the late 1940s when he exhibited with other emerging artists later known as the "Boston Expressionists". .  Called a "master of materials", as both artist and restorer, Gibran turned to sculpture in the mid-fifties.  In 1972, in an effort to separate his identity from his famous relative and namesake, the author of "The Prophet", Gibran Kahlil Gibran, who was cousin both to his father Nicholas Gibran and his mother Rose Gibran, the sculptor co-authored with his wife Jean a biography of the poet entitled "Kahlil Gibran His Life And World".  Gibran is known for multiple skills, including painting; wood, wax, and stone carving; welding; and instrument making. Joseph Alexander Ames (1816–1872) was an American artist, primarily known for portrait and genre painting.  Originally named Joseph Emes, he was born in Roxbury, New Hampshire.  Ames began painting at a young age.  At the age of twelve Henry Theodore Tuckerman wrote about one of his paintings.  After moderate success at home in Saugus, Massachusetts, he left for Boston in 1841.  While in Boston, Ames tried to replicate the style of Washington Allston.  In 1848, Ames traveled to Rome, where he painted a portrait of Pope Pius IX that was featured at the National Academy of Design's annual exhibition in 1850.  When he returned from Italy he was commissioned by Rufus Choate, Daniel Webster, and Abraham Lincoln.  He kept a studio in Boston in Amory Hall (ca.1849), and later on Tremont Street (ca.1856), and then on Summer Street.  Ames exhibited at the Boston Athenæum, the National Academy of Design, and the Pennsylvania Academy.  He eventually moved to Baltimore, and then to New York, where he died of a "brain fever".
