Marsh, a former anchor on WCBS and later WNBC, lost a battle with breast cancer, according to several of her former co-workers. She was born in a Detroit suburb and majored in radio and television production at Northwestern University.
Marsh worked at stations in Maine and Texas before coming to WCBS in New York for a job in October 1979. She ran the teleprompter with her toes while on the air at WABI-TV, the New York Times reported. Marsh was also so popular in her position at a San Antonio station that she had security guards to fend off her admirers.
Marsh was called the "baby of the newsroom" back when she first came to WCBS in New York. Then 25, she co-anchored "The 11 O'Clock Report" with Rolland Smith.
She joked her brown hair had already started turning grey.
She also worked with Ernie Anastos during her time at the station. He remembered her as a "top professional" and a "sweet friend."
She worked there until October of 1996 when she was dismissed along with a host of other anchors and reporters at WCBS-TV. Marsh was quickly hired by WNBC and joined Chuck Scarborough as co-anchor of the 6 p.m. newscasts. She stayed there until 2003. Marsh won five local Emmy Awards in her time working in New York.
"You had 2b living/working in #NYC in '80s-90s 2 appreciate what a big star #MicheleMarsh was at @WCBSTV," WCBS traffic reporter Tom Kaminiski tweeted. "Condolences 2 her family&colleagues."
Meteorologist Craig Allen, another former co-worker, remembered her as "a terrific talent to work with and all around wonderful person."
