NEW YORK – Mark Zuckerberg’s father said in a radio interview Friday that an early exposure to computers inspired his son’s interest in technology, and he encouraged parents to support their children’s strengths and passions with a balance of “work and play.”

“My kids all grew up around the office and were all exposed to computers,” said Dr. Edward Zuckerberg, a dentist. “There are advantages to being exposed to computers early on. That certainly enriched Mark’s interest in technology.”

Zuckerberg said he computerized his offices in 1985. His son Mark Zuckerberg, cofounder and CEO of Facebook, was born in 1984 and was raised in the house where his father’s dental offices are located in Dobbs Ferry, N.Y., in suburban Westchester.

The dentist spoke for an hour on Westchester station WVOX. He said his own computer science background was “limited” — he majored in biology in college — but he said he’s “always been technologically oriented in the office” and “always had the latest high-tech toys,” including an early Atari 800.

“It came with a disk for programming,” he said. “I thought Mark might be interested and I imparted that knowledge to him. From there it took off.”

He said Mark got a book on programming, but “ultimately his ability to program was self-taught.”

A number of callers to the live radio program asked Zuckerberg for advice on parenting.

“Probably the best thing I can say is something that my wife and I have always believed in,” he said. “Rather than impose upon your kids or try and steer their lives in a certain direction, to recognize what their strengths are and support their strengths and support the development of the things they’re passionate about.”

Zuckerberg said he “didn’t believe in physical discipline” but added that certain behaviors require parents to let children know “right there on the spot, this is a behavior that will not be tolerated. If you impart your dislikes about certain negative behaviors early in their lives, they will learn to understand what your feelings on certain matters are.”

Zuckerberg said he doesn’t want to portray himself as an expert on childrearing, but he said: “I think that extremes in any form in parenting are not good. Children need to be well-rounded. There’s a place for work and a place for play.”

He described Mark as “a good student” with “a special affinity for math and sciences,” as well as a “very quiet guy” who “doesn’t like to boast about his accomplishments.”

He said that when Mark was named Time magazine’s person of the year, his famous son remarked that “it must have been a really slow year. He’s very humble.”
