‘All That’ Star Christy Knowings Dies at 46

The actress and comedian appeared in more than 30 episodes of Nickelodeon’s sketch-comedy series before later working on Mother and Child and Sesame Street.
Christy Knowings, best known for appearing on Nickelodeon’s All That, has died at the age of 46. Reports citing a family member said Knowings suffered an asthma attack on Aug. 7, was hospitalized in the Los Angeles area and placed on life support before dying on Aug. 11.

People reported Knowings’ death and hospitalization, citing information initially provided to TMZ by an unnamed family member. The medical details in the reports are therefore attributed to that family source rather than an independently released hospital statement.

Knowings was hospitalized after an asthma attack

According to the reporting, Knowings was admitted to a Los Angeles-area hospital after suffering an asthma attack on Friday, Aug. 7.

She was subsequently placed on life support and died four days later, on Tuesday, Aug. 11.

KTLA also covered the death of the former All That actress at 46, reporting the news as part of its Southern California coverage.

The supplied reports do not include a public statement from a hospital or medical examiner. Details about the asthma attack, hospitalization and life support should therefore remain clearly attributed to the family account cited in the coverage.

Christy Knowings appeared in more than 30 episodes of ‘All That’

Knowings joined All That in 1997 and appeared in more than 30 episodes before making her final appearance on the original series in 1999.

The Nickelodeon program featured comedy sketches performed by a rotating cast of young actors. Other cast members during the show’s run included Kenan Thompson, Amanda Bynes, Kel Mitchell and Nick Cannon.

Knowings’ work on the series introduced her to viewers during a period when All That was one of Nickelodeon’s best-known live-action comedy programs.

An obituary published by The New York Times also looked back at Knowings’ career in children’s television following reports of her death.

After leaving All That, Knowings appeared in the 2009 drama Mother and Child. She also received a writing credit on the film.

Her later television work included three appearances on Sesame Street between 2009 and 2011. Those were her most recent screen credits identified in the supplied reporting.

Kenan Thompson pays tribute to his former castmate

Kenan Thompson, who worked with Knowings on All That, shared a tribute following news of her death.

The tribute reflected the relationships formed among cast members who worked together during the show’s late-1990s run.
