Some birthdays are more memorable than others.

For Trumbull resident Ed Mischik, who was born on Nov. 28, 1915, his 100th birthday last month is one that he — and every Trumbull resident — will always remember.

First Selectman Tim Herbst hosted the Word War II veteran and Purple Heart Award recipient  in his office Tuesday, Dec. 8, which he declared from now on will be known as Ed Mischik Day in town.

“I have hereunto set my hand and caused the seal of the Town of Trumbull to be affixed on the 8th day of December in the year 2015,” Herbst said in a press release.

Mischik, who was born in Bridgeport, moved to Trumbull with his wife, Elsie, in 1941. They had two daughters, Joan and Barbara, along with five grandchildren — Jack, Emma, Luke, Sara and Melanie.

In addition to his distinguished contributions during WWII, Mischik worked as a tool maker at Singers until the plant closed in the 1960s. Following that, he worked for the Town of Trumbull as head custodian at Booth Hill Elementary School until his retirement in 1981.

Students and teachers lovingly referred to him as, “Mr. Ed.”

In a November 2012 article of the Trumbull Times, there was a story stating, “At age 96, he must be the oldest mall walker” — a hobby he’s been doing since 1985.

A faithful fan of  the New York Yankees, the Giants, and UCONN Women’s basketball, Mischik has always been passionate about athletics.

He was very active in Tai Chi, even leading a class for seniors, and still continues to practice Tai Chi at home.

When asked of his secret to a long and healthy life, the 100-year-old man replied, “exercise and Tai Chi.”
