As a teacher, he counts both Brad Mehldau and the Bad Plus' Ethan Iverson as former students. As a player, his nuanced style, influenced by such giants as Ahmad Jamal, Bill Evans, and Oscar Peterson, has garnered him multiple Grammy nominations, and made him a benchmark for modern jazz. Openly gay and diagnosed HIV-positive at age 30, Hersch is a vocal proponent for gay rights and AIDS research and education.

Born in Cincinnati, Ohio in 1955, Hersch began playing classical piano at age four and was dabbling in composing before the age of ten. However, it was while attending Grinnell College in Iowa that he first became interested in jazz. He dropped out of college and spent some time gigging around Cincinnati before enrolling at the New England Conservatory, where he studied with pianist and composer Jaki Byard. After graduating with honors in 1977, Hersch moved to New York City where he began playing nightly, paying his dues as a sideman. He also made his recording debut during this period, appearing on such albums as Art Farmer's Yama and Billy Harper's Awakening, both in 1979.

From 1980 to 1986, Hersch taught at the New England Conservatory. During this time, he began leading his own trio and working as a sideman with such luminaries as Chris Connor, Joe Henderson, Stan Getz, Toots Thielemans, Eddie Daniels, and others. He made his album debut as leader in 1984 with the trio album Horizons, featuring bassist Marc Johnson and drummer Joey Baron. That same year, he paired with clarinetist Jane Ira Bloom for As One; the first of many collaborations between the duo. The '80s remained a busy period for the pianist, who recorded extensively with others, and released his own albums, including 1986's Sarabande, 1988's E.T.C., and 1989's Heartsongs.

In 1993, Hersch came out as gay, announcing the information in his hometown during a benefit performance for AIDS Volunteers of Cincinnati. At the same time, he also revealed that he had been receiving treatment for AIDS since his diagnoses with the disease in 1984. From the '90s onward, Hersch has remained a tireless proponent for both gay rights and AIDS research and education. He has produced benefit recordings, performed in numerous charity concerts, and given keynote addresses at international medical conferences.

The '90s were also the start of a more prolific creative period for Hersch, who earned praise for such releases as 1990's Evanessence: Tribute to Bill Evans, 1992's Dancing in the Dark, and 1994's I Never Told You: Fred Hersch Plays Johnny Mandel. Beginning with 1995's Plays Billy Strayhorn, Hersch built a sturdy set of albums on Nonesuch Records, many of them paying tribute to his influences, including 1996's Plays Rodgers & Hammerstein and 1997's Thelonious Monk-themed Thelonious. Similarly, 1998's Songs We Know found him investigating many of his favorite compositions alongside guitarist Bill Frisell.

In the 2000s, Hersch remained quite active, releasing several highly ambitious works including the three-disc Songs Without Words in 2001 and the Walt Whitman-inspired project Leaves of Grass, which featured contributions from vocalists Kurt Elling and Kate McGarry in 2005. For 2007's Night & the Music, Hersch returned to a more intimate, less conceptual trio setting.

In 2008, Hersch developed HIV-induced dementia, which left him in a coma for two months. Upon awaking, he underwent extensive rehabilitation to help regain his ability to play piano. Following his recovery, he released the bossa nova-themed solo piano effort Fred Hersch Plays Jobim in 2009. The trio recording Whirl appeared on Palmetto in 2010. Also in 2010, Hersch was the subject of a major article in The New York Times Sunday Magazine entitled Giant Steps: The Survival of a Great Jazz Pianist, by David Hadju.

Hersch then delivered two companion live albums with the 2011 solo piano date Alone at the Vanguard, followed a year later by the Grammy-nominated trio album Alive at the Vanguard. 2013 also proved to be a fruitful year as he appeared on no less than three albums: Fun House with pianist Benoit Delbecq, Only Many with trumpeter Ralph Alessi, and Free Flying, a collaboration with guitarist Julian Lage.

In 2014, Hersch received yet another Grammy nomination, for his trio album, Floating. That same year he released the DVD My Coma Dreams, a 2011 performance of his multi-media stage show based on his coma experience. The live album Solo, recorded at the Windham Civic Center Concert Hall in Windham, New York, followed in 2015. In 2016, Hersch was the subject of directors Charlotte Lagarde and Carrie Lozano's documentary film, The Ballad of Fred Hersch. ~ Matt Collar
