On April 30, 1777, German mathematician and physical scientist Carl Friedrich Gauß was born. He who contributed significantly to many fields, including number theory, algebra, statistics, analysis, differential geometry, geodesy, geophysics, electrostatics, astronomy and optics. He is often referred to as Princeps mathematicorum (Latin, "the Prince of Mathematicians") as well as "greatest mathematician since antiquity".
On May 17, 1749, English physician and scientist Edward Anthony Jenner was born, who was the pioneer of smallpox vaccine. He is often referred to as "the father of immunology".
On May 16, 1960, American physicist Theodore Maiman presents the world's first operating laser at Hughes Research Laboratories, Malibu, California. Today, lasers are present everywhere, ranging from common consumer devices such as DVD players, laser printers, and barcode scanners to professional laser devices for surgery and various other skin treatments, or in industry for cutting and welding materials. Actually, it was Albert Einstein, who has laid the theoretical foundations for the laser in his 1917 paper Zur Quantentheorie der Strahlung (On the Quantum Theory of Radiation).
On May 8, 1828, Swiss businessman and social activist Henry Dunant was born. He is best known for the creation of the International Committee of the Red Cross in 1863. Also the 1864 Geneva Convention was based on Dunant's ideas. In 1901 he received the first Nobel Peace Prize together with Frédéric Passy.
In early June 1978 - we have not been able to determine the exact date - the famous arcade video game Space Invaders designed by Tomohiro Nishikado was released by the Japanese Taito Corporation. Space Invaders is one of the earliest shooting games and the aim is to defeat waves of attacking aliens with a laser cannon to earn as many points as possible.
On June 10, 1955, the laying of the foundation stone of the European Organization for Nuclear Research Laboratory (CERN) was performed by Felix Bloch, the organization's first President. Since 1955, numerous essential experiments were executed, leading to significant contributions in the world of physics and to our daily lives.
On October 17, 1604, the famous German astronomer Johannes Kepler started his observations of the 1604 supernova, named after him as Kepler's Supernova or Kepler's Star.
On October 31, 1632, Dutch genre painter Johannes Vermeer was born in Delft. Vermeer always worked slowly and with great care, using bright colours and sometimes expensive pigments, with a preference for cornflower blue and yellow. He is particularly renowned for his masterly treatment and use of light in his work.
On November 30, 1835, famous American author Samuel Longhorn Clemens, better known by his pen name Mark Twain, was born in the tiny village of Florida, Missouri. He is most noted for his humorous novels about the mischievous boys Tom Sawyer and Huckleberry Finn and their adventures on the mighty Mississippi River.
On December 19, 1859, US-american physicist Albert Abraham Michelson was born. Together with his colleague Edward Williams Morley he conducted an experiment that proved the by the time famous ether theory to be wrong and is considered to be one of the pilars of the theory of relativity.
On December 18, 1995, German engineer and computer pioneer Konrad Zuse passed away. He is renowned to have constructed the very functional program-controlled Turing-complete computer, the Z3, which became operational in May 1941.
On January 23, 1840, German physicist, optometrist, entrepreneur, and social reformer Ernst Abbe was born. Together with Otto Schott and Carl Zeiss, he laid the foundation of modern optics. As a co-owner of Carl Zeiss AG, a German manufacturer of research microscopes, astronomical telescopes, planetariums and other optical systems, Abbe developed numerous optical instruments.
On January 19, 1839, French artist and Post-Impressionist painter Paul Cézanne was born. He laid the foundations of the transition from the 19th-century conception of artistic endeavour to a new and radically different world of art in the 20th century. Thus, Cézanne can be said to bridge between late 19th-century Impressionism and the early 20th century's Cubism.
On February 13, 1946, J. Presper Eckert and John Mauchly introduced Electronic Numerical Integrator and Computer, or ENIAC, the first general purpose, electronic computer. ENIAC was a giant step forward in computing technology.
On March 12, 1784, English theologian, geologist and eccentric palaeontologist William Buckland was born, who wrote the first full account of a fossil dinosaur, which he named Megalosaurus.
On April 1, 1976, the original Apple Computer, also known retroactively as the Apple I was demonstrated for the first time in July 1976 at the Homebrew Computer Club in Palo Alto, California. The Apple I was a personal computer released by the Apple Computer Company designed and hand-built by Steve Wozniak. Actually it was Wozniak's friend Steve Jobs, who had the idea of selling the computer. Thus, the Apple I was Apple's first product, and to finance its creation, Jobs sold his only means of transportation, a VW Microbus and Wozniak sold his HP-65 calculator for $500.
On April 17, 1761, English mathematician and Presbyterian minister Thomas Bayes passed away. He is best known as name giver of the Bayes' theorem, of which he had developed a special case. T expresses (in the Bayesian interpretation) how a subjective degree of belief should rationally change to account for evidence, and finds application in in fields including science, engineering, economics (particularly microeconomics), game theory, medicine and law.
On April 20, 1534, French explorer of Breton origin Jacques Cartier set sail under a commission from the king, hoping to discover a western passage to the wealthy markets of Asia to discover Canada and Labrador. Actually, Jacques Cartier was the first European to describe and map the Gulf of Saint Lawrence and the shores of the Saint Lawrence River, which he named "The Country of Canadas", after the Iroquois names for the two big settlements he saw at Stadacona (now Quebec City) and at Hochelaga (now Montreal Island).
On May 23, 1848, German aviation pioneer Otto Lilienthal was born, who was the first person to make well-documented, repeated, successful gliding flights. For his contributions to aviation he is often referred to as "The Father of Flight."
On July 13, 1527, Welsh mathematician, astronomer, astrologer, occultist, navigator, imperialist and consultant to Queen Elizabeth I, John Dee was born. He is considered one of the most learned men of his age. Besides being an ardent promoter of mathematics and a respected astronomer, in his later years he immersed himself in the worlds of magic, astrology and Hermetic philosophy. One of his aims was attempting to commune with angels in order to learn the universal language of creation.
