He was born in Bath, Maine August 24, 1846,[1] graduated with a B.S. at Harvard University in 1869 and at the Hooper Mining School in 1870 also at Harvard.

In 1871 he was almost simultaneously offered positions with Charles Francis Hall on what would become the ill-fated Polaris Expedition or going with Ferdinand Vandeveer Hayden to survey Yellowstone National Park. He chose the Hayden adventure and would map the westen portion of the Hayden's division until 1879.

On July 26, 1872, while climbing the then unnamed highest mountain in the Gallatin Mountains, he and his party experienced electric shocks following a lightning event near the summit. He was to name the mountain Electric Peak.

He married Mary E. Chase on November 24, 1874.[2]

The Father of Government Mapmaking

In 1879 he was among those lobbying for centralizing the mapping functions into one government agency. Previously individual mapmakers and agencies had to compete for money from Congress for funds for projects.

He lobbied to call the new organization "United States Geological and Geographical Survey" although the name United States Geological Survey would officially be approved.

His first job in the new organization under its first director Clarence King was geographer of the United States Census, 1880.[3] He laid out 2,000 enumeration districts with such precision that for the first time each census enumerator knew in advance the metes and bounds of his particular district. The completion of this work on July 1, 1882 is considered the start of true topographical work in the United States and the birth of the quad. He was promoted to Chief Geographer for the Geological Society by John Wesley Powell and would hold the position until 1896.

In 1884 he published his first Dictionary of Altitudes which listed all known survey altitudes in the United States as well as the source of the survey. He was to persuade various organizations doing the surveys including the railroads to begin using similar datums so the data could interconnect.

In 1885 he published Boundaries of the United States and of the Several States and Territories, with a Historical Sketch of the Territorial Changes, which was the first attempt to standardize the history of the boundaries in the country.

In 1888 Gannett was one of founding members of the National Geographic Society.[4] He served as its first secretary, and later as treasurer, then vice-president, and finally president, in 1909. He was also a member of the Washington Academy of Sciences until his death.[5]

He was chief geographer for the United States Census, 1890 and United States Census, 1900

In 1890 he and Thomas Corwin Mendenhall of the U.S. National Geodetic Survey campaigned to establish the United States Board on Geographic Names to create official names for locations in the United States.

In 1893 A Manual of Topographic Methods which was the basis for standardizing survey and mapping processes.

In 1896 in his last year with the USGS, he started the use of the Benchmark.

In 1899, he was invited with other elite scientists on the Harriman Alaska Expedition.

In 1904 he was among the founders of the American Association of Geographers.

In 1906 Gannett Peak, the highest peak in Wyoming, was named for him. In 1911, Lawrence Martin named Mount Gannett, a 10,000-foot peak in the Chugach Mountains of eastern Alaska, for Henry Gannett.

In 1909 he was named chairman of a special committee to examine and verify the records of Robert E. Peary in the controversy with Frederick Cook over who was the first to reach the North Pole.

He was assistant director of the census of the Philippines (1902) and of Cuba (1907–08). From 1897 to 1909, he was a vice president of the American Statistical Association.[6]
