Alexander Graham Bell (1847-1922), inventor of the telephone.  Bell would have been known to history simply as Alexander Bell, but he was highly jealous of his brothers’ middle names and asked for and received one for his 11th birthday. His interest in acoustics developed during his childhood through his experiences with his deaf mother, influencing his later work with the deaf and experimentation with sound.

British biophysicist Rosalind Franklin (1920-1958) took the photo that led to the discovery of the DNA double helix, but all recognition went to male colleagues Watson and Crick.

Rosalind Franklin British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA.

Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian American inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Thomas Alva Edison (1847 – 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb.

"The doctor of the future will no longer treat the human frame with drugs, but rather will cure and prevent disease with nutrition." —Thomas Edison What a smart guy!

Niels Bohr (1885 – 1962) was a Danish physicist who made contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. He was part of the British team of physicists working on the Manhattan Project. One of their sons, Aage Bohr, grew up to be an important physicist who in 1975 also received the Nobel Prize. Bohr has been described as one of the most influential scientists of the 20th century.

Niels Henrik David Bohr 7 October 1885 – 18 November was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in

Henri Becquerel [1852-1908] In 1897 when Henri Becquerel researched the newly discovered X-rays it led to studies of how uranium salts are influenced by light. By accident, he discovered that the uranium salts spontaneously emitted a penetrating radiation that could be registered on a photographic plate. Further studies made it clear that this radiation was something new - not the same type as X-rays. He had discovered a new phenomenon - radioactivity. [by Félix Nadar]

Antoine Henri Becquerel December 1852 – 25 August was a French physicist, Nobel laureate, and the discoverer of radioactivity along with Marie Skłodowska-Curie and Pierre Curie, for which all three won the 1903 Nobel Prize in Physics.

Stephen William Hawking (born 8 January 1942) is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His scientific works include a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity, and the theoretical prediction that black holes emit radiation, often called Hawking radiation.

The Russian chemist Dmitrii Ivanovich Mendeleev (1834-1907) Mendeleev's original work covered a wide range, from questions in applied chemistry to the most general problems of chemical and physical theory. His name is best known for his work on the Periodic Law.

Dmitri Mendeleev - Russian chemist and inventor. He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.

Maria Goeppert Mayer (June 28, 1906 – February 20, 1972) was a German-born American theoretical physicist, and Nobel laureate in Physics for proposing the nuclear shell model of the atomic nucleus. She was the second female Nobel laureate in physics, after Marie Curie.

Gustave Eiffel [1832–1923] was a French civil engineer and architect. He made his name with various bridges for the French railway network, most famously the Garabit viaduct. He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, France. His work can also be seen in the frame of the Statue of Liberty. His contribution to the science of aerodynamics is probably of equal importance to his work as an engineer. [by Félix Nadar in 1888]

Engineered building of the Eiffel Tower. Had an apartment at the top. What a dude.

Ada Lovelace, de son nom complet Augusta Ada King, comtesse de Lovelace, née Anna Byron le 10 décembre 1815 et morte le 27 novembre 1852 à Londres, fille de lord Byron, est principalement connue pour avoir traduit et annoté une description de la machine analytique de Charles Babbage, ancêtre de l'ordinateur. Dans ses notes, on trouve le premier algorithme publié, destiné à être exécuté par une machine, ce qui fait considérer Ada Lovelace comme « le premier programmeur du monde ».

Augusta Ada King, Countess of Lovelace December 1815 – 27 November born Augusta Ada Byron, was an English writer chiefly known for her work on Charles Babbage’s early mechanical.

Émilie du Châtelet  —  Gabrielle Émilie Le Tonnelier de Breteuil, marquise du Châtelet, communément appelée Émilie du Châtelet, née à Paris le 17 décembre 1706 et morte à Lunéville le 10 septembre 1749, est une mathématicienne et physicienne française. Elle est aussi restée célèbre pour être l'auteur de la traduction en français des Principia Mathematica de Newton qui fait toujours autorité aujourd'hui. [par Quentin de La Tour]

Democritus (460 – c. 370 BC) was an influent philosopher primarily remembered today for his formulation of an atomic theory of the universe. He held that nothing could come from nothing, that everything is already in the world and it is merely a matter of combination and re-combination of eternal bits of immutable stuff called atoms that remain indivisible in and of themselves, but are capable by hooks and barbs or balls and joints to combine to other atoms to make up the materials of life.

Democritus (Greek: "chosen of the people") (ca. 460 BC – ca. 370 BC) was an Ancient Greek philosopher born in Abdera, Thrace, Greece. He was an influential pre-Socratic philosopher and pupil of Leucippus, who formulated an atomic theory for the cosmos.

Albert Abraham Michelson, [December 19, 1852 – May 9, 1931] was an American physicist known for his work on the measurement of the speed of light and especially for the Michelson–Morley experiment. In 1907 he received the Nobel Prize in Physics. He became the first American to receive the Nobel Prize in sciences.
