Jacques Seligmann &amp; Co. was founded in Paris, France in 1880 by Jacques Seligmann (1858–1923), a German émigré who arrived in France in 1874 and became a French citizen. The small gallery, located on the Rue du Sommerard quickly became successful and in 1900 moved to a better location: Galerie Seligmann, on the Place Vendôme. Jacques' two brothers, Simon and Arnold, joined the gallery during this time, Simon as accountant and Arnold handling correspondence with clients. Jacques remained manager and handled all purchases. The demand of the American market led the gallery to open a New York office at 7 West 36th St in 1904. In 1909 Seligmann bought the Palais de Sagan in Paris, which served as the showcase venue for large exhibitions and client visits. Early notable clientele included Edmond James de Rothschild, the Stroganov family, Philip Sassoon, Benjamin Altman, William Randolph Hearst, J. P. Morgan, Henry Walters, and Joseph Widener.
