New York, NY  -  GVA Williams, a leading commercial real estate advisory services firm, announced today the completion of two lease renewal transactions at 415 Madison Avenue and 41 Madison Avenue on behalf of Holtzbrinck Publishers.

Scientific American, Inc., a major magazine company owned by Holtzbrinck Publishers, renewed its lease at 415 Madison Avenue, where it has conducted business since the office building opened 50 years ago.  It renewed its lease for more than 31,000 square feet comprising nearly two and a half floors for another ten years.

In another transaction, Bedford Freeman & Worth, college publishers also part of Holtzbrinck Publishers, renewed its lease for more than 28,000 square feet at 41 Madison Avenue.  The space is comprised of two full floors and a portion of the basement.  The company, which has been a tenant in the building since 1982, has signed on for another ten years. 

Robert L. Freedman, president and CEO, Leon Manoff, executive managing director and Marvin Rosenberg, managing director of GVA Williams represented the tenants in both transactions.  Rudin Management Company represented itself.

“We are very pleased to have negotiated the lease extensions for Scientific American and Bedford Freeman and Worth Publishers,” said Freedman. “Madison Avenue continues to be an ideal location for high-profile publishing companies, and are we pleased to have secured these prominent offices at 415 and 41 Madison for yet another decade.”  Added Manoff, “After an exhaustive search for suitable alternatives, we concluded that these tenants were already occupying the space best suited for them.  Both companies had an excellent relationship with the Rudin organization and everyone was pleased that those relationships will continue.”

Holtzbrinck Publishers is the U.S. operations of the German publishing company, Verlagsgruppe Georg von Holtzbrinck Gmbh, and is one of the largest publishers in the world, with such book companies as St. Martin’s Press, Tor, Henry Holt, Picador and Farrar, Straus & Giroux.  Scientific American, which it also publishes, was founded in 1845 and is today the oldest continuously published monthly magazine in the United States.

These leases were part of a series of transactions aggregating approximately 350,000 square feet negotiated by GVA Williams on behalf of a host of Holtzbrinck entities.
