Most people know Kevin James from The King of Queens or the Paul Blart: Mall Cop films. Fewer people know that his real name is Kevin George Knipfing — and that the Knipfing name traces back to a quiet, private New York father named Joseph Valentine Knipfing Jr.
This article looks at who Joseph Valentine Knipfing Jr. was, where his family came from, and how his two sons ended up becoming well-known names in American comedy. It also answers a question that comes up often in searches: why does Kevin James go by a different name than the one he was born with?
Who Was Joseph Valentine Knipfing Jr.?
Joseph Valentine Knipfing Jr. was a private individual. He was not a public figure, did not have a documented entertainment career, and was not famous in his own right. Most people who search his name are really trying to understand the family background behind Kevin James or Gary Valentine.
Based on available genealogy and celebrity biography sources, Joseph Valentine Knipfing Jr. was born in 1930 and passed away in 2006. He spent his life in New York, connected to the Long Island area, and raised a family there.
The clearest way to understand him is as the family root behind two sons who both found success in comedy. He is not the central story — but without him, the story does not exist.
The Knipfing Family Line and German Roots
Joseph Valentine Knipfing Jr. did not appear out of nowhere. He was part of an established New York family with documented roots going back at least one more generation.
His father was Joseph Valentine Knipfing Sr., and his mother was Helen Josephine Wolf. The family had German ancestry on the Knipfing side, which genealogy sources and celebrity ethnicity profiles tie back through Kevin James’ paternal line. The surname itself is consistent with German-origin family names that arrived in the United States through immigration.
Joseph Sr. and Helen had several children together. According to records from Find a Grave and FamilySearch, the siblings in that generation included Joseph Jr., William, George, and Vincent. The family was based in New York, which fits naturally with where Joseph Jr. would later raise his own children.
Genealogy records are always worth reading with some care — small details can vary between sources. But the broad outline here, a German-rooted New York family producing Joseph Valentine Knipfing Jr. in 1930, is supported by multiple independent sources.
His Marriage and the Three Knipfing Children
Joseph Valentine Knipfing Jr. married a woman named Janet Klein, who became Janet Klein Knipfing. Together, they built a family in New York and had three children.
Their children were:
- Gary — born Gary Joseph Knipfing, later known publicly as Gary Valentine
- Kevin — born Kevin George Knipfing, later known publicly as Kevin James
- Leslie — the third sibling, who has stayed out of the public spotlight
The family lived a relatively ordinary life by all accounts. They were not an entertainment household. There is no record of Joseph Jr. or Janet having careers in show business or any particular connection to the entertainment industry.
What makes the family unusual, in hindsight, is that two of their three children ended up building careers in comedy and acting. That kind of sibling pairing is genuinely rare in American entertainment.
Gary Valentine, born Gary Joseph Knipfing, went on to work as a stand-up comedian and actor. Kevin James, born Kevin George Knipfing, became one of the more recognizable comedy actors of his generation. Leslie Knipfing, by contrast, has remained private, and there is very little public information to report about her.
Kevin James and the Story Behind the Stage Name
One of the most common questions people ask when they find this family is simple: why is he called Kevin James and not Kevin Knipfing?
The answer is straightforward. Kevin James was born Kevin George Knipfing. When he moved into professional comedy, he adopted a stage name. “Kevin James” comes from his first name and his middle name — not from a different family or a legal name change tied to personal reasons.
This is not unusual in entertainment. Many performers shorten, alter, or restructure their birth names when they start working professionally. Sometimes it is about ease of pronunciation. Sometimes it is about fitting a name to a marquee. In Kevin James’ case, the name he chose was already right there in his full birth name.
The connection between “Kevin James” and “Kevin George Knipfing” is why searches for Kevin James’ real name so often lead people to his father’s full name. People find “Knipfing,” wonder where it comes from, and start tracing the family tree — which eventually leads them to Joseph Valentine Knipfing Jr.
Kevin James’ career is well-documented and does not need much introduction. He starred for nine seasons in The King of Queens on CBS, which aired from 1998 to 2007. He followed that with Paul Blart: Mall Cop in 2009, which became a significant box office success. He has continued working in film and television since then. All of that fame attached to a man born with the surname Knipfing is exactly why that surname now attracts steady search interest.
Gary Valentine: The Other Famous Son
Gary Valentine is sometimes overlooked in conversations about the Knipfing family because Kevin James is significantly more famous. But Gary’s career is worth noting here because it reinforces the same family connection.
Born Gary Joseph Knipfing, Gary Valentine is a comedian and actor who appeared on The King of Queens alongside his brother. His character on that show, Doug Heffernan’s friend Danny, meant that both Knipfing brothers were regularly appearing on the same CBS sitcom — one using a stage name, the other also performing under a different professional name.
Gary Valentine has also done stand-up comedy and appeared in other television and film projects. Like Kevin, he adopted a stage name rather than performing under the Knipfing surname.

Why Joseph Valentine Knipfing Jr. Attracts Search Interest
It is worth being direct about this: Joseph Valentine Knipfing Jr. is not famous. He was a private person who lived a private life in New York and passed away in 2006. There is no documented public record of a career, a public role, or any celebrity status of his own.
The reason his name appears in searches is almost entirely because of his sons. When people search for Kevin James’ birth name, they find “Kevin George Knipfing.” When they search for the Knipfing surname, they find the family line leading back to Joseph Jr. and Joseph Sr. before him.
This is a common pattern in celebrity genealogy searches. A famous person’s background becomes interesting to fans and curious readers, and the search eventually lands on a quiet family member who never sought any public attention at all.
Joseph Valentine Knipfing Jr. fits that description well. He was the father, the family anchor, the person behind the name — not the performer.
A Private Life, A Public Legacy Through His Children
There is not a great deal more to say about Joseph Valentine Knipfing Jr. as an individual, and that is appropriate. The public record on him is thin by design — he was not a public person, and the sources that mention him do so only in the context of his more famous sons.
What can be said is this: he was born in 1930, he came from a German-rooted New York family, he married Janet Klein, and he raised three children in New York. Two of those children, Gary and Kevin, went on to build real careers in American comedy. He passed away in 2006, according to available sources, before some of his sons’ most prominent later work.
The Knipfing name, which both famous sons chose not to carry into their professional lives, is still the thread that connects all of them. And that thread starts with Joseph Valentine Knipfing Jr. — a private man whose family became, by accident of his children’s talent, a small piece of entertainment history.
