Mark Goddard might be best known for his role as Major Don West on the 1960s TV show “Lost in Space,” but his work with children has eclipsed his accomplished acting career. He eventually left show business to go back to school, and earned a master’s degree in education from Bridgewater State College. He now works as a special education teacher at the F.L. Chamberlain School in Middleborough, teaching students behavioral management skills, and the occasional improv workshop. “I’ve always been involved in working with young people,” said Goddard, who lives in Bridgewater with his wife and their 16-year- old son. “It’s a wonderful facility, with kids from all over the Northeast,” he said. “I work very closely with them.” Goddard said that, in between his acting gigs on the West Coast and on Broadway, he found time to work with children at Head Start programs in California and at the Memorial Sloan-Kettering Cancer Center in New York. He occasionally makes appearances at trade shows to sign autographs for “Lost in Space” buffs, and he still receives fan mail from time to time. He recently began writing a memoir (working title: “To Space and Back”) about his acting career, and his early days growing up in Scituate, including his varsity basketball days at Scituate High, and teenage pranks that led to run-ins with Weymouth police.
