Firm history
KlingStubbins was formed through the merger of two offices. The first, The Kling-Lindquist Partnership, Inc., was founded by Vincent Kling in 1946, and grew to become the largest firm in Philadelphia. One of the most recognizable buildings designed by Kling is the Bell Atlantic Tower, which was completed in 1991 and remains among the tallest buildings in Philadelphia. Kling also collaborated with Philadelphia city planner Edmund Bacon. The Stubbins Associates was founded by Hugh Stubbins, FAIA, in 1949 and based in Cambridge, MA. Hugh Stubbins had designed several of the world's most noted skyscrapers, including the Citicorp Center in New York City, the Federal Reserve Bank of Boston headquarters in Boston, and the Yokohama Landmark Tower, the tallest building in Japan.Kling became affiliated with The Stubbins Associates in 2003, and the two officially merged on January 1, 2007. The company has grown to include engineering, interior design, landscape architecture, and several branch offices in other cities. In 2011, KlingStubbins was acquired by Jacobs and operates as part of their Global Buildings sector.
