Jon Provost
“I have some sad news, we have lost another movie and television icon, my TV mom, June Lockhart has passed. June and I worked together on lassie from 1958 to 1964, she truly was my second mother.
I remember some advice June gave me early on. We were on the set and I was misbehaving a bit, being a little mischievous. June took me aside, and very firmly explained to me that we were professionals and that we had a job to do. She told me that I was a young boy playing a young boy, but that one day I would be an adult, playing an adult like her. June was a true professional, with a kind heart and an open mind.
We kept in touch all these years after Lassie until recently, we never missed a Birthday card, Christmas card and phone calls.
Love you June, and I will miss you a bunch.

Bill Mumy
“Goodbye to the brilliant June Lockhart. A one of a kind, talented, nurturing, adventurous, and non compromising Lady. She did it her way. June will always be one of my very favorite moms. 100 years here. Wow! R.I.P.

Angela Cartwright
“I was so very sad to hear that June Lockhart has passed away. She played my mom on ‘Lost in Space’, and I’ll always treasure our time together on and off the screen. So smart, quick, and funny — she filled her 100 years with curiosity, laughter, and rock ‘n’ roll.
I can only imagine she’s feeling right at home as she steps off this planet and into the stars.
