Content:  Quakers. In 1740 he invents the Franklin stove, refusing a patent on the device because it was for "the good of the people". He proposes an academy, which opens after money is raised by subscription for it and it expands so much that a new building has to be constructed for it. Franklin obtains other governmental positions (city councilman, alderman, burgess, justice of the peace) and helps negotiate a treaty with the Indians. After helping Dr. Thomas Bond establish a hospital, he helps pave the streets of Philadelphia and draws up a proposal for Dr. John Fothergill about doing the same in London. In 1753 Franklin becomes Deputy 
Title: Science and technology in the United States
Content:  In the early decades of its history, the United States was relatively isolated from Europe and also rather poor. At this stage, America's scientific infrastructure was still quite primitive compared to the long-established societies, institutes, and universities in Europe. Eight of America's founding fathers were scientists of some repute. Benjamin Franklin conducted a series of experiments that deepened human understanding of electricity. Among other things, he proved what had been suspected but never before shown: that lightning is a form of electricity. Franklin also invented such conveniences as bifocal eyeglasses. Franklin also conceived the mid-room furnace, the "Franklin Stove". However, Franklin's design was flawed, in that his furnace vented the smoke from its base: because the

"Benjamin Franklin's ingenuity gained in strength as did his cunning and in 1737 he had replaced his counterpart in Pennsylvania, Andrew Bradford as postmaster and printer after a competition he instituted and won. He showed his prowess by running an ad in his General Magazine and the Historical Chronicle of British Plantations in America (the precursor to the Saturday Evening Post) that stressed the benefits offered by a stove he invented, named the Pennsylvania Fireplace. His invention is still sold today and is known as the Franklin stove. " American advertising initially imitated British newspapers and magazines. Advertisements 
Title: Thomas Jefferson
Content:  Jefferson invented many small practical devices and improved contemporary inventions, including a revolving book-stand and a "Great Clock" powered by the gravitational pull on cannonballs. He improved the pedometer, the polygraph (a device for duplicating writing), and the moldboard plow, an idea he never patented and gave to posterity. Jefferson can also be credited as the creator of the swivel chair, the first of which he created and used to write much of the Declaration of Independence. As Minister to France, Jefferson was impressed by the military standardization program known as the Système Gribeauval, and initiated a program as president to develop interchangeable parts for firearms. For his inventiveness and ingenuity, he received several honorary Doctor of Law degrees.

He is the inventor of, among other things, a frog exaggerator (which grossly misrepresents the size of amphibians), automatic tapping shoes for tap dancing, the sarcasm detector, hamburger earmuffs, the 8-month-after pill, and a drilling machine that can cut through anything. Some of Frink's unsuccessful inventions include his small remote-controlled plane that carries babies as passengers (it crashed),, the "Gamble-Tron 2000," a machine designed to predict pro football scores (after it predicts one team will win by

Among the most notable inventors were Jan Matzeliger, who developed the first machine to mass-produce shoes, and Elijah McCoy, who invented automatic lubrication devices for steam engines. Granville Woods had 35 patents to improve electric railway systems, including the first system to allow moving trains to communicate. Garrett A. Morgan developed the first automatic traffic signal and gas mask. Lewis Howard Latimer invented an improvement for the incandescent light bulb. More recent inventors include Frederick McKinley Jones, who invented the movable refrigeration unit for food transport in trucks and trains. Lloyd Quarterman worked with six other Black scientists on the creation of the atomic bomb (code named the Manhattan Project.) Quarterman also helped develop the 
Title: Charles Samuel Franklin
Content:  Franklin was born in London, the youngest of a family of 13, and educated at Finsbury Technical College in Finsbury, England, under Silvanus P. Thompson. After graduation in 1899 he joined the Marconi Company where he spent his entire professional career. He was first sent to South Africa to provide equipment for the Boer War, then spent 2 years in Russia. After his return to the UK, he invented a number of important radio devices including the variable capacitor (patented 1902), ganged tuning (1907), variable coupling (1907), coaxial cable, and the Franklin oscillator. Today Franklin is best known for the Franklin beam aerial, his shortwave antenna.
