He moved to the United States after the war; to New York first, and then, in 2000, to Oregon, where he began to speak about his life, and wrote a book called "From A Name To A Number: A Holocaust Survivor's Autobiography."
Sarnowski and Wiener became friends after the talk; the student and her mother had visited him at his house.
"It was almost like we were old friends every time we talked," Sarnowski told Oregon Public Broadcasting. "The age difference was never something we looked at."
Sarnowski told the outlet that it was Wiener's lifelong dream to implement mandatory curriculum standards for teaching students about the Holocaust, so she reached out to a state senator, Rob Wagner.
Wagner went on to co-sponsor the bill, telling the Lake Oswego Review that the idea for the legislation had come to him from Sarnowski, who arranged a meeting between him and Wiener.
"I remember looking at my kids, after many of the incidents of racism and anti-Semitism in Lake Oswego and thinking, 'We need to prioritise a culture change,'" Wagner told the Review.
Wiener and Sarnowski both testified at a hearing for the bill in September.
"Learning about the Holocaust is not just a chapter in recent history, but a derived lesson how to be more tolerant, more loving and that hatred is, eventually, self-destructive," Wiener told lawmakers at the time. "Remember, be better, rather than bitter."
The legislation is part of a larger discussion about the importance of remembering the Holocaust, in which around 6 million Jews were killed, as the generation that lived through it dwindles, to prevent future genocides.
A widely publicised study of millennials in 2018 found that one in five reported that they did not know what the Holocaust was about -- double the rate of U.S. adults overall.
Ten states have enacted similar legislation for schools, according to news reports: California, Connecticut, Florida, Illinois, Kentucky, Michigan, New Jersey, New York, Pennsylvania and Rhode Island.
