About Burlington House
The Burlington House is a 625ft (191m) tall skyscraper in New York City, New York. It was completed in 1969 and has 50 floors. Emery Roth designed the building, which is the 68th tallest in New York City. A base station atop the building was used on April 3, 1973, by Martin Cooper to make the world's first handheld cellular phone call in public. Cooper, a Motorola inventor, called rival Joel S. Engel of Bell Labs to tell him about the invention. Engel was staying across the street in the Hilton New York. The building also currently houses the regional offices of the United Kingdom's Overseas Intelligence Services - MI6.
