After retiring from teaching, he took over the role of Edward Quartermaine on the ABC daytime drama in 1993, after original actor David Lewis retired due to health issues.
Ingle was fired from the soap in 2003, and Edward was reportedly going to be killed off, but fan support led to Ingle being rehired as the patriarch. In 2004, Ingle left General Hospital to take over the role of Mickey Horton on Days of Our Lives. He returned to GH as Edward in 2006 and made his final appearance in the soap just last week.
