The Kent community is mourning the death of a longtime Theodore Roosevelt High School chemistry teacher who was hit by a sport-utility vehicle while riding a bicycle.

Mitch Lambert, 56, of Rootstown, died Monday from the injuries he received when he was struck from behind by an SUV on Wednesday morning on Lynn Road in Rootstown, according to the Ohio State Highway Patrol. No charges had been filed against the SUV driver as of Tuesday afternoon

A memorial service will be held at the school’s auditorium at 1 p.m. Sunday.

"Dr. Lambert is truly going to be missed as a science teacher and chemistry teacher at Roosevelt. He did work for us for 27 years and not only was he a teacher, but he was a building leader when it came to students and all of the things that are right about Roosevelt. He definitely will be missed," Kent Superintendent George Joseph said.

Lambert taught chemistry for 32 years. He also worked as an adjunct professor at Kent State University, his alma mater. His father, Bob Lambert, also taught science at Davey Junior High and then at Roosevelt.

"So sad to hear this. Mitch comes from a family of WONDERFUL teachers," Donna Ruttan wrote in a post on the Record-Courier's Facebook page. "My heart breaks for his family."

Counselors were available at the high school Tuesday to talk with students, staff and community members.

Lambert received various accolades including Teacher of the Year four times at Roosevelt, most recently in 2017, the Martha Holden Jennings Scholar Award for Excellence in Teaching in 2003 and the Gene Easter Award in 2017, for which he was nominated by high school Principal Dennis Love.

"Mitch was an incredible person, an incredible man, an outstanding teacher. He was a mentor to so many people in this building, whether it was to administrators, other teachers or students," Love said. "He was so kind, so caring. He wanted everyone to be mentally healthy. He wanted everyone to be the best version of themselves. He worked extremely hard at making people's lives better, and so many people loved Dr. Lambert. It's so sad for us here at the high school and the community. We're just thinking about and praying for his family and his kids."

Others expressed similar sentiments on social media.

"He was such an inspiration to my son. Dr. Lambert is the reason he is majoring in biochemistry. We are forever thankful for his impact and guidance in our son's life," Laura Pool Cope wrote in a Facebook post.

Said Denise Gemberling: "Such a nice man and a great teacher. He will be missed."
