In 1886, the Purdue Student Army Training Corps, forerunner of the
Reserve Officers Training Corps, formed a five-member drum corps to play music for the cadets during their morning conditioning marches. Purdue fielded its first football team a year later, in 1887. The band began playing at games soon afterward. However, during this time it played sporadically, as there was no consistent director; it depended on finding a student or faculty member who was qualified to drill them. Additionally, the band received almost no training and had to provide most of their own equipment and support. Despite this, by 1902 it had grown to 50 members and had become partly self-supporting. Despite the lack of a full-time director, it was already known as one of the best college bands in the nation. The band's modern history began in 1904 when
Paul Spotts Emrick, a freshman engineering student from
Rochester, joined the band. His experience as a conductor (and indeed, one of the few members with any musical background at all) resulted in his election as band president and director the next year. During his senior year at Purdue in 1907, the band began forming a giant block "P" during its pregame drill. It was the first time that a band had broken ranks to form a letter on the field. In a 1953 interview with the Lafayette
Journal & Courier, Emrick recounted seeing geese fly over a lake in the fall, saying "usually, they'd fly in a 'V', but once in a while, they'd change formation and fly in various figures. I used to wonder if you could do that with men drilling." The now-famous "Block P" has been performed during each pregame show ever since its inception. Emrick stayed on as full-time director after his graduation in 1908. In 1921 Emrick commissioned the
Leedy Manufacturing Company of
Indianapolis to construct the world's largest bass drum. The "
Big Bass Drum" has been a part of the marching band ever since. In 1935, during a Purdue football game at
Northwestern University the band donned lights on their uniforms while performing at halftime. With the stadium lights turned off for the performance, the band drew such awe from radio broadcaster
Ted Husing, he referred to them as a "truly All-American marching band," hence the current title of the band. Emrick retired in 1954, and to date the band has been under the direction of just four other men full time: • Dr.
Al G. Wright (1954–1981) •
William C. Moffit (1981–1988) • Dr. David A. Leppla (1989–2006) • Jay S. Gephart (July 1, 2006 – 2025) During this time, there have also been two interim directors: • Joseph Manfredo (1988–1989) • Dr. Matt Conaway (2025–present) Second director Al Wright added many "show band" traditions to the "All-American" Marching Band. He increased the size of the band, added baton twirlers, and changed the uniform to its current look. Wright built upon the patriotism suggested in the "All-American" name of the band by creating the "I Am An American" speech. This speech is read during each pre-game performance while the band plays
America the Beautiful. Wright greatly increased the visibility of the "All-American" Marching Band across the world by taking the band to perform in many countries including Canada, Holland, Germany, Iceland, Japan, Colombia, and Venezuela during the 1960s and 1970s. This tradition of international travel continues today, with other notable trips including an invitation from the Chinese government to perform in international cultural activities that lead up to the
2008 Beijing Summer Olympics. In 2012, 2018 and 2023 the Band also traveled to Ireland for the Saint Patrick's Day Parade in Dublin. In 2015, the AAMB traveled to Medellin, Colombia for the
Feria de las Flores. In 1995 the "All-American" Marching Band was the recipient of the
Sudler Trophy, the most prestigious award a college marching band can receive. Currently, the "All-American" Marching Band is the only band from a university without a school of music to have received this award. After Jay Gephart's retirement as director after the 2024 season, associate director Matt Conaway was appointed as the band's interim director for the 2025 season and a search for the band's next director was carried out. In January 2026, Purdue dropped the "interim" tag from Conaway's title and named him the band's sixth full-time director, beginning in the fall of 2026. ==Featured Twirlers==
