Not for any one single invention but for the design, development, building and launching of a near global radio navigation system in the 1940s,that originated from Cambridge Massachusetts, that helped turn the course of the war in Europe and in the Pacific, that Within a matter of years, a complex radio navigation system called loran went on the air to create e a network for ship- borne navigators to find their way across the North Atlantic. Using the same technology,during the same period, the radio navigation system was extended for coverage in the Pacific Ocean. Loran was a totally new American system of navigation pressed into service during the 1940s used by thousands of navigators over three-tenths of te surface of the earth (1946). | ||
The Boston Section is proposing the | The Boston Section is proposing the Loran Milestone because the initial design and development of this unique system of radio navigation took place in Cambridge Massachusetts during 1940 to 1945. Scientific research, engineering, procurement of apparatus, field surveys, installation and testing transmitting equipment, training of technicians and operators, all were under the direction of persons working for the Radiation Laboratory of the Massachusetts Institute of Technology. Their scope of work slowly decreased as loran stations came on line. By 1945, the Radiation Laboratory contract was terminated but work on loran continued by others. | ||

Pierce acknowledges the existance of the British gee system under development in the early 1940s. Gee operated on the same principal. He also acknowledges that "Loran copied gee's concepts rather than techniques and may be said to have been invented in America in the sense in which Galileo is said to have invented the telescope". | Pierce acknowledges the existance of the British gee system under development in the early 1940s.

The | The SPEED OF EXECUTION in which the loran system of navigation was researched, designed, developed, constructed, placed into operations, manned 24/7 by radio technicians at isolated regions of the globe, is hard to explain. Even for a well-funded wartime crash program. Authors of this milestone proposal are not aware of anything similar to loran. | ||

By 1 October 1942 a chain of four loran transmitting stations in the US and Nova Scotia were on the air. Loran receivers began to be shipped and installed on selected naval vessels and a group of radio technicians were sent to training schools in Cambridge. | By 1 October 1942 a chain of four loran transmitting stations in the US and Nova Scotia were on the air.

John (Jack) A. Pierce, who retired from a position as a senior research fellow at Harvard University, Cambridge, Mass. was awarded the Medal For Engineering Excellence in 1990 for the "design , teaching and advocacy of radio propagation, navigation and timing which led to the development of Loran, Loran C and Omega." In 1941, Pierce began working at the Massachusetts Institute of Technology's Radiation Laboratory which was testing the United States' first hyperbolic radio aid to navigation called Loran. It inaugurated in October 1942. Later work produced Loran C which operated at a lower frequency of 100 kHz. After WWII, he was appointed senior research fellow in applied physics at Harvard and from 1950 to 1974 did work on low frequency navigation aids that lead to Omega. | John (Jack) A.
