John Mark Galecki was born in Bree, Belgium, to American parents; his father was stationed there while serving in the U.S. Air Force. When he was three years old, his family moved to Chicago, Illinois, where he grew up with his parents, Mary Lou and Richard Galecki, and siblings, sister Allison . He isn't on twitter, and Galecki once said, "I don't understand the current frame of mind in our society that seems to say that any action is not of value until it's broadcast somehow." He still lives in Los Angeles but is often spotted in Chicago, where his siblings still live.
Born in Belgium where his father was stationed while serving in the US Air Force. He moved to Chicago when he was 3 years old.
In 1991, he starred in the made-for-TV movie Backfield in Motion , which co-starred the production team of Roseanne Barr and Tom Arnold. The next year, Galecki joined the cast of "Roseanne" as Darlenes sensitive and put-upon boyfriend, David.
At the age of 11, he received a Joseph Jefferson citation nomination for his critically-acclaimed performance as "John Henry" in "The Member of the Wedding".
By age 7, he began performing in such prestigious theater productions as "Fiddler on the Roof", "Pippin" and "Galileo", opposite Brian Dennehy at The Goodman Theater in Chicago.
Star/producer/writer Roseanne Barr of "Roseanne" praises Galeckis "great vulnerability".

He is a vegetarian.
Was considered for the role of John "Doc" Bradley in Flags of Our Fathers .

Guest-starred on "Blossom" with Mayim Bialik , from "The Big Bang Theory" , as her date in 1991. In 2011, their characters dated again in "The Big Bang Theory" {The Pulled Groin Extrapolation (#5.3)} episode of "The Big Bang Theory" .
Is 6 years, to the day, older than his "The Big Bang Theory" co-star, Kunal Nayyar.
Former smoker. He quit shortly before the eighth season of "The Big Bang Theory" began. He started smoking when he was only a teenager.
Used a pin to poke a hole through his ear lobe at the age of ten because his parents would not allow him to get his ear pierced professionally.
Eventually, that became something. The way they wrote it and the way I,played it. And it fortunately played so well off the "Darlene",character, too. My spinelessness and her strength.
We have Nobel Prize winners asking if they can guest-star on the show.
