He returned to New York in November 1839 and in that month, according to the testimony of his son Harry, made a portrait with a camera invented by Wolcott. This camera portrait he believed to be the first ever made. In 1840, after more experimenting, he set up a studio in Baltimore, where his father was then living, and spent several years there “taking likenesses.” At the same time he continued to work with telescopes and lenses. His first refractors were built there, instruments he later referred to as crude affairs. While in Baltimore he took a step which marks the beginning of the final phase of his career. In June 1844 he married Julia Ann Wells of Southold, Long Island, whom he had known for about a decade and with whom he had long corresponded. Julia was a woman of unusual ability and personality, less scientific than he but more literary and artistic, and no less intelligent. With her to encourage him, he continued his experiments in telescope building. A year after their marriage they moved to New York, where he was to spend the remainder of his life. That summer he prepared a 6-inch refracting telescope for exhibition at the Fair of the American Institute, held annually in New York. This carefully constructed instrument, with its ingenious tripod and its achromatic objective—which he had made himself, correcting the curves by a process of his own invention—won the highest award of the Fair, a gold medal. It was the first of many such medals he was to earn. His telescope also received favorable notice from scientists and astronomers, among them Lewis M. Rutherfurd, a wealthy New Yorker and trustee of Columbia College. Rutherfurd immediately ordered a 4-inch refractor for his own observatory. His interest and example soon brought orders from others. From this time on, Henry Fitz devoted most of his energies to building telescopes. Cameras were not altogether abandoned. He continued to make them and to instruct others in their use. He invented a camera lens that was patented posthumously. He was one of the founders of the American Photographical Society and remained interested in it all his life. But from 1845 on, cameras became secondary; he built them between telescope orders. [Illustration: FIGURE 10.—Henry Fitz made this 13-inch equatorial refractor in 1861 for the Allegheny Observatory.
