Wonder Woman star Gal Gadot honored her grandfather, a Holocaust survivor, in a touching tribute she posted to Instagram on Israel’s National Holocaust Remembrance Day.

Gadot honored her grandfather Abraham Weiss in a very personal post. She wrote, “Even though he went thru hell. Lost his ENTIRE family in Auschwitz.. He chose to believe in good. I miss you saba. I love you.”

She would add, “I’ve never seen this video before and it made me cry. And as I think of you today, at this very moment of remembrance, which is also a call for all of us to act against discrimination of any kind. Anywhere in the world.”

I was looking for a photo of you all night on my phone but I couldn't find one, so I wanted to ask mom to send me one but she didn't answer..that's the annoying thing about traveling.. There's always something you need that you left back home. And then I got into the car, going to work out with stunts and meetings with PJ for WW, and Katy, my assistant goes "Hi, I found this real sweet video of you and I think your grandpa".. She had no idea today is the holocaust remembrance day, and didn't know I was looking for a photo of him/us all night… I wasn't surprised.. My grandpa is always with me.. That's not the first time he pops out of nowhere.. That's how he used to be.. With his special sense of humor and always there for us. Even though he went thru hell. Lost his ENTIRE family in Auschwitz.. He chose to believe in good. I miss you saba. I love you. And thanks for helping out with finding a photo of us. I've never seen this video before and it made me cry. And as I think of you today, at this very moment of remembrance, which is also a call for all of us to act against discrimination of any kind. Anywhere in the world.

This isn’t the first time Gadot has spoken publicly about her grandfather. She remembered him in another Instagram post from last year.

She would write, “Grandpa.. I miss you , hero. You left us 3 years ago but your legacy is living with us forever. My grandfather was born in 1928 in a small village named Muncaks in Czechoslovakia. His ENTIRE family was brutally vanished in WW2. Just because someone had decided they were born into the wrong religion and race.”

Gal Gadot passionately continued, “My grandpa taught me there is NO wrong religion . No wrong color . And no wrong race. I was taught to love all people for what their heart is.”

She concluded, “We’re all spirits and souls in this universe . Light should always beat darkness as love should always beat hatred. Today we remember and never forget.”
