He was one of four Links who never joined the Photo-Secession, the others being F. Holland Day, Margaret Russell Foster, and C. Yarnall Abbott. In 1900, Eickemeyer joined the New York Camera Club, and exhibited 154 frames in his first one-man show at the club. That same year, he published his first book, "Down South", and was appointed art manager of the Campbell Art Studio on Fifth Avenue, with which he would remain intermittently until 1915. It was while at Campbell that Eickemeyer conducted his famous shoot of New York model Evelyn Nesbit. Eickemeyer was awarded the gold medal for photography at the St. Louis World's Fair in 1904. The following year, he purchased half of the photographic firm, Davis and Stanford (renamed Davis and Eickemeyer), which operated out of a studio at 246 Fifth Avenue. In 1911, Eickemeyer was commissioned by William Randolph Hearst to photograph American wives of British peerage as part of the coronation ceremonies of King George V.  Eickemeyer hosted a restropective of his work at the Anderson Galleries in New York in 1922, and made his last submissions to the London Salon in 1926. In 1929, he donated most of his best-known photographs to the Smithsonian Institution. The following year, he served as a judge in Kodak's international photography competition alongside Thomas Edison, John J. Pershing, Richard E. Byrd, and Benito Mussolini. He died at St. John's Hospital in Yonkers in 1932. The Hudson River Museum in Yonkers has a collection of over 200 examples of Eickemeyer's photography. As a pictorialist, Eickemeyer believed photographs were works of art. However, he believed in producing straightforward images and using natural elements to produce artistic effects instead of using photographic techniques (such as soft focus) to imitate traditional art. He was described by photography critic Sidney Allen as the "most versatile" pictorialist of his time, and excelled in both landscapes and portraits. In 1893, Eickemeyer's photographs, "Lily Gatherer" and "As She Comes Down the Stairs" (for which his wife, Isabelle, posed) won silver medals at the Joint Annual Exhibition in Philadelphia, and the latter won the gold medal at the Hamburg International Exhibition. In 1894, Eickemeyer won sixteen medals in ten international exhibitions, including the Royal Photographic Society's Albert Medal for his "Sweet Home".
