| Galton, Peter M. Peter M. Galton is a British paleontologist working in the USA. He named: Aliwalia (1985), Blikanasaurus (with J. van Heerden, 1985), Bugenasaura (1995), Callovosaurus (1980), Camelotia (1985), Dracopelta (1980), Gravitholus (with W. P. Wall, 1979), Lesothosaurus (1978), Ornatotholus (with H. Sues,1983), Othnielia, (1977), Stygimoloch (with H. Sues,1983), Torvosaurus (with J.A. Jensen, 1979), Valdosaurus (1977), and Yaverlandia (1971). He named the dinosaur families: Blikanasauridae (with J. van Heerden, 1985), Fabrosauridae (1972), Staurikosauridae (1977), and Ruehleia (2001). He named the order Herrerasauria (1985). He also championed the cladistic theory that birds are modern-day dinosaurs (with R. Bakker, 1974), showed that Hypsilophodon was not arboreal (did not live in trees), that hadrosaurs did not drag their tails but used the tail as a counterbalance for the head, and that the Pachycephalosaurs butted heads like rams. |
| Garces, Francisco Father Francisco Tomás Garcés, (April 12, 1738 - July 18, 1781) was a Spanish Franciscan priest who was a missionary and explorer. Father Garces explored the southwestern part of North America, including what is now Arizona, U.S., southern California, and the Gila and Colorado rivers (including the western Grand Canyon). He visited Hopi and Havasupai Indians, learning much about the area. From 1768 to 1776, Father Garces explored with Juan Bautista de Anza and alone with native guides. He and Juan Díaz died in a Yuman uprising in the area where the Colorado and Gila rivers meet; they were trying to find a route from Sonora, Mexico to California. |
| Gilmore, Charles W. Charles Whitney Gilmore (1874-1945) was a scientist who studied North American and Asian dinosaurs (including those in the Gobi Desert), and fossil lizards. He named Alamosaurus (1922), Alectrosaurus (1933), Archaeornithomimus (1920), Bactrosaurus (1933), Brachyceratops (1914), Chirostenotes (1924), Mongolosaurus (1933), Parrosaurus (1945), Pinacosaurus (1933), Thescelosaurus (1913), and the family Troodontidae (1924). Gilmoreosaurus (Brett-Surman, 1979) was named to honor Gilmore. |
Glenn, John John Glenn (1921-2016) piloted the first American manned orbital mission on February 20, 1962. He flew NASA's Friendship 7, a Mercury-Atlas 6 spacecraft, to about 162 miles in altitude, going at a maximum orbital velocity of about 17,500 miles per hour. This mission orbited the Earth 3 times and lasted 4 hours, 55 minutes, and 23 seconds, from launch to impact in the Atlantic Ocean. In 1998, 36 years later, Glenn flew a 9-day mission on the Space Shuttle (STS-95). Glenn was the US Senator from Ohio from 1974 to 1998.

| Gray, Robert Robert Gray (1755-1806) was a American explorer who had previously been in the Navy during the Revolutionary War. Gray sailed from Boston, Massachusetts, in 1787, and traveled around South America to the northwest coast of North America and on to China, where he traded furs for tea. He began his journey with Captain John Kendrick on a sister ship. Gray continued west and returned to Boston in 1790. Gray was the first American-born explorer in an American ship to circumnavigate the globe. In 1791, he led another expedition to the northwest coast on a ship called "Columbia." In 1792, Gray sighted, named, and sailed up the Columbia River in Oregon, and also explored Gray's Harbor in what is now the state of Washington. Because of Gray's exploration, the United States now laid claim to the Oregon territory. Gray again continued westwards and circumnavigated the globe again, returning to Boston in 1793. |

Joseph Gayetty invented toilet paper in 1857. His new toilet paper was composed of flat sheets. Before Gayetty's invention, people tore pages out of mail order catalogs - before catalogs were common, leaves were used. Unfortunately, Gayetty's invention failed. Walter Alcock (of Great Britain) later developed toilet paper on a roll ( instead of in flat sheets). Again, the invention failed.
Virgil "Gus" Ivan Grissom (April 3, 1926 - January 27, 1967) was one of the original seven NASA astronauts. Grissom flew the second manned US space flight, commanded the first two-man Gemini mission, and was killed along with Edward White II and Roger Chaffee in a launch pad fire during a test for the upcoming first Apollo flight, which Grissom was scheduled to command.
