William Patrick Corgan Jr. (born March 17, 1967) is an American guitarist, singer, songwriter, and professional wrestling promoter. He is best known as the co-founder, lead guitarist, primary songwriter, singer, and only constant member of alternative rock band The Smashing Pumpkins. Corgan is credited with helping popularize the alt rock genre. He has also been the owner and promoter of the National Wrestling Alliance since 2017. Corgan formed the Smashing Pumpkins in Chicago in 1988 alongside guitarist James Iha, with bassist D'arcy Wretzky and drummer Jimmy Chamberlin joining soon after. Strong album sales and large-scale tours propelled the band to commercial success and critical acclaim throughout the 1990s. After their break-up in 2000, Corgan and Chamberlin started a new band called Zwan; after the band's demise, he released the collection of poetry Blinking with Fists (2004) and the solo album TheFutureEmbrace (2005) before reforming Smashing Pumpkins in 2007. The new version of the band, consisting of Corgan and a revolving lineup, has released new albums and toured extensively. In October 2017, Corgan released Ogilala, his first solo album in over a decade. His latest solo album, Cotillions, was released in 2019. Corgan co-founded Resistance Pro Wrestling in 2011. He joined TNA Wrestling in 2015 and became its president in 2016, but left a few months later. He purchased the National Wrestling Alliance (NWA) in 2017; thereafter, Corgan made it his primary focus in professional wrestling.
