Popular Philadelphia artist and Lower Merion School District art teacher died suddenly on Christmas Day, said officials with the school district in an open letter on its website.
Todd Marrone, art and gifted education teacher, was at Welsh Valley Middle School for 16 years.
His work in pop art, digital media, mixed media, cartoons and more captured the eyes of art gallery owners around the city, where his work was frequently shown.
School Principal Chris Hall said crisis counselors will be in place when students return to school late this upcoming week.
Marrone was 39 years old and leaves behind a wife and two children.
