Erasmus Darwin Leavitt, Jr.
Erasmus Darwin Leavitt Jr. (October 27, 1836 – March 11, 1916), also known as E. D. Leavitt, was a noted American mechanical engineer best known for his steam engine designs. Life and work Leavitt was born in Lowell, Massachusetts to Erasmus Darwin Leavitt Sr., a native of Cornish, New Hampshire, and Almina (Fay) Leavitt. He graduated from local schools at age 16, and performed a 3-year apprenticeship at the Lowell Manufacturing Company. After his apprenticeship Leavitt worked for one year at the engineering firm of Corliss & Nightingale in Providence, Rhode Island before returning to Boston, where he became assistant foreman for Harrison Loring. In this role he designed the steam engine for the USS '' Hartford''. From 1859–61 he again worked in Providence, this time as chief draftsman for Thurston, Gardner & Company, builders of steam engines. During the Civil War, Leavitt first served aboard the USS '' Sagamore'', then in construction roles in Baltimore, Bost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henrietta Swan Leavitt
Henrietta Swan Leavitt (; July 4, 1868 – December 12, 1921) was an American astronomer. A graduate of Radcliffe College, she worked at the Harvard College Observatory as a "computer", tasked with examining photographic plates in order to measure and catalog the brightness of stars. This work led her to discover the relation between the luminosity and the period of Cepheid variables. Leavitt's discovery provided astronomers with the first "standard candle" with which to measure the distance to faraway galaxies. Before Leavitt discovered the period-luminosity relationship for Cepheid variables, the only techniques available to astronomers for measuring the distance to a star were based on parallax and triangulation. Such techniques can only be used for measuring distances up to hundreds of light years. Leavitt's work allowed astronomers to measure distances up to about 20 million light years. As a result of this, it is now known that our own galaxy, the Milky Way, has a diamet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bethlehem Steel Company
The Bethlehem Steel Corporation was an American steelmaking company headquartered in Bethlehem, Pennsylvania. For most of the 20th century, it was one of the world's largest steel producing and shipbuilding companies. At the height of its success and productivity, the company was a symbol of American manufacturing leadership in the world, and its decline and ultimate liquidation in the late 20th century is similarly cited as an example of America's diminished manufacturing leadership. From its founding in 1857 through its 2003 dissolution, Bethlehem Steel's headquarters and primary steel mill manufacturing facilities were based in Bethlehem, Pennsylvania in the Lehigh Valley region of the United States. The company's steel was used in the construction of many of America's largest and most famed structures. Among major buildings, Bethlehem produced steel for 28 Liberty Street, the Chrysler Building, the Empire State Building, Madison Square Garden, Rockefeller Center, and the Wal ...

Louisville, Kentucky
Louisville ( , , ) is the largest city in the Commonwealth of Kentucky and the 28th most-populous city in the United States. Louisville is the historical seat and, since 2003, the nominal seat of Jefferson County, on the Indiana border. Named after King Louis XVI of France, Louisville was founded in 1778 by George Rogers Clark, making it one of the oldest cities west of the Appalachians. With nearby Falls of the Ohio as the only major obstruction to river traffic between the upper Ohio River and the Gulf of Mexico, the settlement first grew as a portage site. It was the founding city of the Louisville and Nashville Railroad, which grew into a system across 13 states. Today, the city is known as the home of boxer Muhammad Ali, the Kentucky Derby, Kentucky Fried Chicken, the University of Louisville and its Cardinals, Louisville Slugger baseball bats, and three of Kentucky's six ''Fortune'' 500 companies: Humana, Kindred Healthcare, and Yum! Brands. Muhamm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calumet And Hecla Mining Company
The Calumet and Hecla Mining Company was a major copper-mining company based within Michigan's Copper Country. In the 19th century, the company paid out more than $72 million in shareholder dividends, more than any other mining company in the United States during that period. History In 1864, Edwin J. Hulbert discovered a copper-bearing section of what became known as the Calumet Conglomerate of Precambrian age. The find was in Houghton County, Michigan, between the rich Cliff mine to the northeast, and the copper mines of Portage Lake to the southwest, but a long way from either. Hulbert formed the Hulbert Mining Company in 1864 to acquire the land rights, before creating the Calumet Company in 1865, with Boston investors. The company spun off the Hecla Company the following year, and assigned shares in the new company to Calumet shareholders. Hulbert was a major shareholder in both companies, and was in charge of mine operations. But despite the rich ore, Hulbert did not hav ...

Erasmus Darwin
Erasmus Robert Darwin (12 December 173118 April 1802) was an English physician. One of the key thinkers of the Midlands Enlightenment, he was also a natural philosopher, physiologist, slave-trade abolitionist, inventor, and poet. His poems included much natural history, including a statement of evolution and the relatedness of all forms of life. He was a member of the Darwin–Wedgwood family, which includes his grandsons Charles Darwin and Francis Galton. Darwin was a founding member of the Lunar Society of Birmingham, a discussion group of pioneering industrialists and natural philosophers. He turned down an invitation from George III to become Physician to the King. Early life and education Darwin was born in 1731 at Elston Hall, Nottinghamshire, near Newark-on-Trent, England, the youngest of seven children of Robert Darwin of Elston (1682–1754), a lawyer and physician, and his wife Elizabeth Hill (1702–97).
