Hector's clingfish, "Gastroscyphus hectoris", is a clingfish of the family Gobiesocidae, the only species in the genus Gastrocyathus.
 It is found all down the east coast of New Zealand around the low water mark amongst seaweed, on rocky coastlines.
 Its length is up to 6.4 cm SL.
 It is named after Scottish-born scientist James Hector.
Robert Fulton (November 14, 1765 – February 24, 1815) was an American engineer and inventor who is widely credited with developing a commercially successful steamboat called "The North River Steamboat of Claremont".
 That steamboat went with passengers from New York City to Albany and back again, a round trip of 300 miles, in 62 hours in 1807.
 In 1800, he was commissioned by Napoleon Bonaparte to attempt to design the "Nautilus", which was the first practical submarine in history.
 He is also credited with inventing some of the world's earliest naval torpedoes for use by the British Royal Navy.
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor, self-described "Father of Radio", and a pioneer in the development of sound-on-film recording used for motion pictures.
 He had over 180 patents, but also a tumultuous career—he boasted that he made, then lost, four fortunes.
 He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud.
 His most famous invention, in 1906, was the three-element "Audion" (triode) vacuum tube, the first practical amplification device.
 Although De Forest had only a limited understanding of how it worked, it was the foundation of the field of electronics, making possible radio broadcasting, long distance telephone lines, and talking motion pictures, among countless other applications.
Claude Chappe (December 25, 1763 – January 23, 1805) was a French inventor who in 1792 demonstrated a practical semaphore system that eventually spanned all of France.
 This was the first practical telecommunications system of the industrial age, making Chappe the first telecom mogul with his "mechanical internet."
Alexander Graham Bell Fairchild (August 17, 1906–February 10, 1994) was an American entomologist, and a member of the Fairchild family, descendants of Thomas Fairchild of Stratford, Connecticut and one of two grandsons of the scientist and inventor, Alexander Graham Bell, for whom he was named, and son of David Fairchild, a botanist and plant explorer.
Louis Charles Joseph Blériot (1 July 1872 – 1 August 1936) was a French aviator, inventor and engineer.
 He developed the first practical headlamp for trucks and established a profitable business manufacturing them, using much of the money he made to finance his attempts to build a successful aircraft.
 In 1909 he became world-famous for making the first flight across the English Channel in a heavier than air aircraft, winning the prize of £1,000 offered by the "Daily Mail" newspaper.
 Blériot was also the first to make a working, powered, piloted monoplane and was the founder of a successful aircraft manufacturing company.
Charles Bourseul (28 April 1829 – 23 November 1912) was a pioneer in development of the "make and break" telephone about 20 years before Bell made a practical telephone.
Charles Franklin Kettering (August 29, 1876 – November 25, 1958) sometimes known as Charles "Boss" Kettering was an American inventor, engineer, businessman, and the holder of 186 patents.
 He was a founder of Delco, and was head of research at General Motors from 1920 to 1947.
 Among his most widely used automotive developments were the electrical starting motor and leaded gasoline.
 In association with the DuPont Chemical Company, he was also responsible for the invention of Freon refrigerant for refrigeration and air conditioning systems.
 At DuPont he also was responsible for the development of Duco lacquers and enamels, the first practical colored paints for mass-produced automobiles.
 While working with the Dayton-Wright Company he developed the "Bug" aerial torpedo, considered the world's first aerial missile.
 He led the advancement of practical, lightweight two-stroke diesel engines, revolutionizing the locomotive and heavy equipment industries.
 In 1927, he founded the Kettering Foundation, a non-partisan research foundation.
 He was featured on the cover of Time Magazine on January 9, 1933.
Mabel Gardiner Hubbard (November 25, 1857 – January 3, 1923), was the daughter of Boston lawyer Gardiner Greene Hubbard, who was the first president of the Bell Telephone Company.
 As the wife of Alexander Graham Bell, an eminent scientist and the inventor of the first practical telephone, she took the married name Mabel Bell.
Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a Scottish-born scientist, inventor, engineer, and innovator who is credited with patenting the first practical telephone and founding the American Telephone and Telegraph Company (AT&T) in 1885.
