circumstances in 1874. As a result, Henry O. Flipper of Georgia became the first black graduate in 1877, graduating 50th in a class of 76. Two of the most notable graduates during this period were George Washington Goethals from the class of 1880, and John J. Pershing from the class of 1886. Goethals gained prominence as the chief engineer of the Panama Canal, and Pershing would become famous for his exploits against the famed Pancho Villa in Mexico and later for leading American Forces during World War I. Besides the integration of southern-state and black cadets, the post-war academy also struggled with the issue of hazing. In its first 65 years, hazing was uncommon or non-existent beyond small pranks played upon the incoming freshmen, but took a harsher tone as Civil War veterans began to fill the incoming freshman classes. The upper class cadets saw it as their duty to "teach the plebes their manners." Hazing at the academy entered the national spotlight with the death of former cadet Oscar L. Booz on 3 December 1900. Congressional hearings, which included testimony by cadet Douglas MacArthur, investigated his death and the pattern of freshmen's systemic hazing. When MacArthur returned as superintendent, he made an effort to end the practice of hazing the incoming freshmen by placing Army sergeants in charge of training new cadets during freshman summer. The practice of hazing continued on some levels well into the late 20th century, but is no longer allowed in the present day. The demand for junior officers during the Spanish–American War caused the class of 1899 to graduate early, and the Philippine–American War did the same for the class of 1901. This increased demand for officers led Congress to increase the Corps of Cadets' size to 481 cadets in 1900. The period between 1900 and 1915 saw a construction boom as much of West Point's old infrastructure was rebuilt. Many of the academy's most famous graduates graduated during the 15-year period between 1900 and 1915: Douglas MacArthur (1903), Joseph Stilwell (1904), Henry "Hap" Arnold (1907), George S. Patton (1909), Dwight D. Eisenhower, and Omar Bradley (both 1915). The class of 1915 is known as "the class the stars fell on" for the exceptionally high percentage of general officers that rose from that class (59 of 164). The outbreak of America's involvement in World War I caused a sharp increase in the demand for
