Because of the coronavirus pandemic, WISN 12 had to pause its Top Teacher segment that highlighted educators across southeastern Wisconsin. But one retiring Franklin teacher, whose last day of school was Thursday, got so many nominations, WISN 12 went to find out why, and it's out-of-this-world."I figured out the other day that I've been going to school for 52 years, so I think it's time to stop," Franklin High School English teacher Kevin Nettesheim said. In his final days of his 34-year career, Nettesheim said his goodbyes, while also looking back on the thousands of papers he's graded, the hundreds of games he's coached and all of the Franklin students who have sat at the desks."One of my former students, I point out regularly in my classroom. She hated reading and writing, didn't want to do it and so we went back and forth all through freshman year about how important it was to communicate," Nettesheim said.But with the desire to be a rocket scientist, Amber Gell was skeptical."Several years passed, and I get a phone call from out of the blue, and she said, 'Hi Mr. Nettesheim, this is Amber, do you remember me?' And I said, 'Of course, I remember you. You're the rocket scientist.' And she responds 'Yes, I am,'" Nettesheim said."I work for a large contractor that is a prime contractor to NASA on some of their main human space flight programs," Gell said.But Gell said her English teacher made such an impression on her that she put his name on a satellite sent into space."Little did I realize the English and the literature and how I much I would enjoy it, and how many times I would still leverage the stuff he taught me and the references today," Gell said.Which means his legacy will continue for years to come on earth and beyond."People always go back and forth. Follow your passion, don't follow your passion, follow your passion. Do what you want to do. Follow your dreams," Nettlesheim said.Nettesheim's family crunched some numbers. They believe he's taught, coached and empowered the lives of more than 5,000 students in the last 34 years.Although Thursday was Nettesheim's last day, he said it likely won't sink in until the start of the next school year.
