Mr. Chamberlin, became the National Geographic Society's chief cartographer in 1961. and retired in 1971. He invented the Chamberlin trimetric projection a method of showing large areas of the earth with less distortion than conventional projections. He also designed the plastic geometer, or measuring that fits over the society's world globe, and enables the user to compute direction, distance, area, mileage, time and even the position of the sun and the orbit of satellite. Mr. Chamberlin, a graduate of Antioch College, joined the society's cartographic staff as a researcher in 1935. In 1946, he perfected the Chamberlin trimetric projection, a technique based on the surveyor's axiom that a point can he definitely located by its distance from three other points. His projection, used by cartographers throughout the world, allows the mapping of entire continents minimum distortion. Gilbert Hovey Grosvenor (October 28, 1875 - February 4, 1966), father of photojournalism, was the first full-time editor of National Geographic Magazine (1899-1954). Grosvenor is credited with having built the magazine into the iconic publication that it is today. As President of the National Geographic Society, he assisted its rise to one of the world's largest and best known science and learning organizations, aided by the chronicling in its magazine of ambitious natural and cultural explorations around the globe. Grosvenor was hired in 1899 as the first full-time employee of the National Geographic Society by Alexander Graham Bell, the Society's President at the time. He eventually was named Director, and later President of the Society, and remained Editor of the magazine until 1954. Grosvenor advocated policies of neutrality and positive, upbeat journalism through two world wars, the Great Depression, and the beginning of the Cold War. This style was seen as innovative in the opening years of the 20th century. However, by the 1950s, Grosvenor's style was criticized as being ossified and dated. He became very involved in protecting the Katmai volcanic crater and Valley of Ten Thousand Smokes from mining exploitation, and helped to establish Katmai National Monument in 1918.
