Templeton won a
National Merit Scholarship, and Buffington helped him to apply to the
Kansas City Art Institute. He was accepted and arrived in
Kansas City in 1946 at the age of seventeen. During that year Templeton was awarded the Vanderslice scholarship. Early on, Templeton was able to cover his living expenses with portrait commissions. He spent his summers in Colorado, honing his skill in portraiture on the sidewalks of
Estes Park. In Kansas City he came under the influence and tutelage of
Thomas Hart Benton, who sat for him for his portrait. Templeton had gone to the Benton home for the sitting, and when the sketch was finished, Benton called in his daughter to get her reaction to the portrait. When she approved, Benton was delighted, and autographed it. In the summer of 1949 Templeton traveled to
Santa Fe, New Mexico, to visit with the artist
John French Sloan and his wife Helen. A lifelong friendship developed from that visit, and when Templeton moved to New York to continue his studies at the
Art Students League of New York, Sunday afternoon teas and discussions about art at the Sloan home became a regular event in Templeton's life. With a letter of recommendation from John Sloan, Templeton was able to get a Ball Grant from the Art Students League two years in a row. He attended classes in the Fall, Winter, and Spring, and he supplemented his income by ushering at
Carnegie Hall. He continued to spend summers as a sidewalk artist in Estes Park, which generated enough income to last him through the school year. == Army service ==
