Justus Freiherr von Liebig [a] (12 May 1803 – 18 April 1873) [2] was a German scientist who made major contributions to the theory, practice, and pedagogy of chemistry, as well as to agricultural and biological chemistry; he is considered one of the principal founders of organic chemistry. [3]
Rudolf Christian Karl Diesel (English: / ˈ d iː z əl ˌ-s əl /, [1] German: ⓘ; 18 March 1858 – 29 September 1913) was a German [note 1] inventor and mechanical engineer who invented the Diesel engine, which burns Diesel fuel; both are named after him.
The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's Difference Engine, which was a design for a simpler mechanical calculator.
1837: Charles Babbage proposes a design for the construction of a Turing complete, general purpose Computer, to be called the Analytical Engine. 1838: Matthias Schleiden: all plants are made of cells. 1838: Friedrich Bessel: first successful measure of stellar parallax (to star 61 Cygni). 1842: Christian Doppler: Doppler effect.
Oliver Evans was born in Newport, Delaware on September 13, 1755, to Charles and Ann Stalcop Evans. His father was a cordwainer by trade, though he purchased a large farm to the north of Newport on the Red Clay Creek and moved his family there when Oliver was still in his infancy. [1]
The incomplete Difference Engine No. 1 was put on display to the public at the 1862 International Exhibition in South Kensington, London. [13] [14] Babbage went on to design his much more general analytical engine, but later designed an improved "Difference Engine No. 2" design (31-digit numbers and seventh-order differences), [9] between 1846 ...
Samuel Martin Kier (July 19, 1813 – October 6, 1874) was an American inventor and businessman who is credited with founding the American petroleum refining industry. He was the first person in the United States to refine crude oil into kerosene lamp oil. [1]
The Akroyd engine was the first functional internal combustion engine that could use petroleum oil as fuel. [8] It was operational in 1891, six years before the Diesel engine first ran. However, after the Diesel engine had proven successful, Diesel engine became the synonym for an engine that ran on any sort of petroleum oil.
