Rush’s family shared in an official statement that he had been living with chronic heart issues for the past three years, and his passing was unexpected but calm, with no pain in his final hours. Rush launched his acting career at the age of 5, when he was scouted for a national cereal commercial during a local school talent show. His breakthrough role came two years later, in 1957, when he was cast as 7-year-old Lon Chaney Jr. in the Oscar-nominated biopic *Man of a Thousand Faces*, opposite Hollywood legend James Cagney, who played the iconic silent film makeup artist Lon Chaney Sr. Critics at the time praised Rush’s raw, authentic performance, noting that he held his own against A-list co-stars and perfectly captured the confusion and pride of a young boy navigating his father’s unusual, high-pressure career. Rush reached even wider mainstream fame for his recurring role as Howie Pruitt, best friend of Ron Howard’s character Opie Taylor, on the hit CBS sitcom *The Andy Griffith Show*, appearing in 12 episodes between 1961 and 1964. His warm, playful portrayal of the small-town Mayberry kid made him a fan favorite, with viewers tuning in especially for his silly on-screen antics with Howard and other child cast members. He also made guest appearances on other classic 1960s series including *Leave It to Beaver*, *My Three Sons*, and *The Donna Reed Show* before stepping away from the entertainment industry entirely at age 16 to focus on his education. After earning a bachelor’s degree in elementary education from the University of California, Los Angeles, Rush worked as a 3rd grade teacher in Los Angeles public schools for 38 years, retiring in 2018. He rarely spoke publicly about his acting career during his time as an educator, and only occasionally appeared at *The Andy Griffith Show* fan conventions and classic Hollywood nostalgia events over the past two decades. His family noted that he often said his proudest achievement was not his early acting success, but the thousands of students he supported and mentored during his teaching career. He is survived by his wife of 51 years, two children, and four grandchildren.
