June Lockhart, a popular actress of the 1950s and ’60s known for her roles in “ Lost In Space ,” “ Lassie ” and “Meet Me in St. Louis,” died of natural causes on Oct. 23 in Santa Monica, Calif. She was 100.

The actress had amassed more than 150 film and television credits during her career.

Like a real-life Lassie, Eeyore potentially saved his owner’s mother’s life. As the Okaloosa County Sheriff’s Office wrote in a statement, “It was a faithful four-legged friend who brought an OCSO deputy to her location.”
