The original hotel started as two hotels on Fifth Avenue built by feuding relatives. The first hotel, the 13-story, 450-room Waldorf Hotel, designed by Henry Janeway Hardenbergh in the German Renaissance style, was opened on March 13, 1893, at the corner of Fifth Avenue and 33rd Street, on the site where millionaire developer William Waldorf Astor had his mansion. The original hotel stood high, with a frontage of about on Fifth Avenue, with an area of . The original hotel was described as having a "lofty stone and brick exterior", which was "animated by an effusion of balconies, alcoves, arcades, and loggias beneath a tile roof bedecked with gables and turrets". William Astor, motivated in part by a dispute with his aunt Caroline Webster Schermerhorn Astor, had built the Waldorf Hotel next door to her house, on the site of his father's mansion. The hotel was built to the specifications of founding proprietor George Boldt, who owned and operated the Bellevue-Stratford Hotel, a fashionable hotel on Broad Street in Philadelphia, Pennsylvania, with his wife Louise. Boldt was described as "Mild mannered, undignified, unassuming", resembling "a typical German professor with his close-cropped beard which he kept fastidiously trimmed... and his pince-nez glasses on a black silk cord". Boldt continued to own the Bellevue even after his relationship with the Astors blossomed.
