Early Amarican scientist.Lets talk about it..

Franklin, one of the first early American scientists.
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.

Two 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 furnace lacked a chimney to "draw" fresh air up through the central chamber, the fire would soon go out. It took David R. Rittenhouse, another hero of early Philadelphia, to improve Franklin's design .

Thomas Jefferson :(1743-1826), was among the most influential leaders in early America; during the American Revolutionary War (1775–83), Jefferson served in the Virginia legislature, the Continental Congress, was governor of Virginia, later serving as U.S. minister to France, U.S. secretary of state, vice president under John Adams (1735-1826), writer of the Declaration of Independence and the third U.S. president. During Jefferson’s two terms in office (1801-1809), the U.S. purchased the Louisiana Territory and Lewis and Clark explored the vast new acquisition. After leaving office, he retired to his Virginia plantation, Monticello, and helped spearhead the University of Virginia.[4] Jefferson was also a student of agriculture who introduced various types of rice, olive trees, and grasses into the New World. He stressed the scientific aspect of the Lewis and Clark expedition (1804–06),[5] which explored the Pacific Northwest, and detailed, systematic information on the region's plants and animals was one of that expedition's legacies

Like Franklin and Jefferson, most American scientists of the late 18th century were involved in the struggle to win American independence and forge a new nation. These scientists included the astronomer David Rittenhouse, the medical scientist Benjamin Rush, and the natural historian Charles Willson Peale.[6]

During the American Revolution, Rittenhouse helped design the defenses of Philadelphia and built telescopes and navigation instruments for the United States' military services. After the war, Rittenhouse designed road and canal systems for the state of Pennsylvania. He later returned to studying the stars and planets and gained a worldwide reputation in that field.
