Carl Hammer (1914-2004) was born in Chicago, Illinois, on May 10, 1914, to Karl and Kaethe Hammer, who had emigrated from Germany in 1912. He was educated in Germany from 1920 and returned to the United States in 1938 after finishing his PhD program in mathematical statistics and probability theory.

Hammer’s first job was at the Beacon Laboratories of Texaco Corporation in New York. From 1943 to 1951, he taught at Columbia University’s Bureau of Applied Social Research. Hammer left New York City for a consulting job at the Franklin Institute in Philadelphia where he had an opportunity to work with Grace Murray Hopper, who headed one of two major software departments at Remington-Rand [[UNIVAC|Univac]]. He also helped I. Edward Block, Donald Haughton, and Donald Hay in founding the Society for Industrial and Applied Mathematics, and served as its treasurer in 1955. When Remington Rand was planning on opening a UNIVAC I Computer Center in Frankfurt am Main, Germany, Hammer interviewed for and got the job as its first director and moved there in 1956. When he returned to the United States in 1957, Hammer took a job with Sylvania Electronic Products in Needham, Massachusetts. Sylvania used a UNIVAC I in support of its defense business, and had a contract to design, develop, and deliver a state of-the-art mobile computer for the US Army Signal Corps to support the distribution of intelligence around the battlefield—known as the Fieldata project. This project used a computer housed in a large trailer, known as MOBIDIC (for mobile digital computer). Hammer created scientific models for MOBIDIC intelligence applications and worked on other Sylvania projects such as the Universal Digital Operational Flight Trainer and the KX3, an encryption device used by government agencies.


''On 11 July 1962 this site transmitted the first transatlantic TV signal to a twin station in Pleumeur-Bodou, France via the TELSTAR satellite. The success of TELSTAR and the earth stations, the first built for active satellite communications, illustrated the potential of a future world-wide satellite system to provide communications between continents.''
After meeting with Univac Washington Vice President Leland E. (Lee) Johnson, Hammer agreed to join Sperry Univac Federal Government Marketing in Washington, D.C., on January 2, 1963, as director of Computer Sciences. He traveled to Univac offices around the globe, to lecture and provide technical advice. He also lectured at the US State Department, the FBI Academy, the Industrial College of the Armed Forces, and other private and public organizations.

Carl Hammer contributed to professional organizations, including the Data Processing Management Association (DPMA), the American Federation of Information Processing Societies (AFIPS), and the National Computer Conference (NCC). He was also instrumental in creating the International Conferences on Computer Communication in 1972 and 1974.  


The site of the Andover Earth Station was selected by AT&amp;T in December 1960. The main factors were the topography of the land and the radio interference signal level. Other factors included a location in the Northeast United States to give a short great circle path to Western Europe, it was located close enough to existing transcontinental radio relay television and telephone routes to facilitate interconnection. In addition, the site had to be large enough to accommodate an antenna structure and control building, and provide for expansion, if necessary.
Hammer pioneered the use of computers and provided leadership to numerous professional and industry organizations throughout his career. He passed away on January 24, 2004, in Washington, D.C.  


Land was purchased in January, 1961, and construction of the complex began on 1 May. Building construction was completed and the equipment was installed in February 1962. The Ground Station was operational in the Spring of 1962. AT&amp;T and Bell Labs initiated, funded, constructed and took the leadership to make this project possible.

The Andover Earth Station was equipped with a giant horn antenna,&nbsp;seven stories high and weighing three hundred and forty tons. To protect it from bad weather, a radome made of Dacron covered the antenna. It was one hundred and sixty&nbsp;feet high, two hundred and ten feet wide and weighed thirty tons.

Telstar was launched on 10 July 1962 from the Cape Canaveral Air Force Station, which is located at the Kennedy Space Center, located on Cape Canaveral in Florida, and went into orbit at 4:46 am. The engineers at the Andover Earth Station would have to wait&nbsp;fifteen hours for the satellite, traveling at a rate of&nbsp;five miles per second, 3000 miles above the earth to reach within their "view." The engineers successfully sent a signal to Telstar, which amplified it&nbsp;ten billion times and relayed it back to Andover.


[[Oral-History:Eugene O'Neill|Eugene F. O'Neill]], Telstar Project Director and [[IEEE Fellow Grade History|IEEE Fellow]], oversaw the success of this project at Andover. He noted, in his IEEE oral history, that one of the challenges was pointing an extremely sharp beam very accurately at the satellite. At 7:17 pm he announced "We've acquired Telstar!" At 7:31 pm an American flag at Andover appeared on the television screen. Then at 7:47 pm engineers at Andover received word that the France site, Pleumeur-Bodou, had received the television picture. History had been made.
