Elaine Hall, founder of the Miracle Project, will speak about her unconventional approach to helping children with autism in a free lecture Wednesday at 4:15 p.m. at the League School of Greater Boston, 300 Boston Providence Turnpike. Hall was a children’s acting coach who adopted an autistic son from a Russian orphanage. When traditional therapies didn’t work for him, she helped develop a method that uses the performing arts. Hall is the author of “Now I See the Moon: A Mother, A Son, and the Miracle of Autism.” For additional information, contact Anne Haubenat ahauben@leagueschool.com or 508-850-3900, ext. 512.
