So I’m absolutely thrilled by this recognition. No other actress has received this honor.“ae0fcc31ae342fd3a1346ebb1f342fcb Speaking to NPR in 2004, she said, that astronauts have told her that Lost in Space inspired them in their careers. “I did Lassie for six years and I never had anybody come up to me and say, ‘It made me want to be a farmer,’” she joked.

Speaking to the Fayette Tribune in 2014, Lockhart reminisced about her first movie, 1938’s A Christmas Carol—which she starred in with both of her actor parents, Gene and Kathleen Lockhart—and watching it with her family now. “My daughter, Junie, and granddaughter, Christianna, have never let me forget that the first words I ever spoke in movies were: ‘I know, I know–sausages!’ It’s become a family joke and we all shriek with laughter when we watch it now,” she said. “Watching the film has become a family tradition each year. And now, to be able to watch it with my grandchildren—well, who gets to do something like that?” When she spoke with The Daily Item in 2015, Lockhart opened up about her perspective on life. “I’ve had many opportunities that just dropped into my lap over the years and I’m glad I was equal to them,” she said. “I used to think 90, gosh, that’s old. But I feel 55. I’m very fortunate to still be active and working.” RELATED: See Little Ricky, the Last Living Cast Member of I Love Lucy, All Grown Up.
