I was born in 1856 in Columbus, Ohio. I hold patents on more than 35 electrical and mechanical inventions, and am known as the person most responsible for modernizing the railroad.

Granville T. Woods. Woods, an African-American, patented a 'third rail' system, an airbrake system, an electronic car powered by overhead lines, to name a few.

I was born in Croatia in 1856 and emigrated to the U.S. in 1884. I invented fluorescent lighting, the alternating current (AC) system and a coil which carries my name that is still in use in radio and TV sets.

Nikola Tesla. A rock group from Sacramento named themselves TESLA.

I was born in Vienna, Austria in 1878 and was head of the physics department at the Kaiser-Wilhelm Institute in 1917. I escaped Germany for Sweden in 1938 where I coined the term 'fission' after my nephew and I split the uranium nucleus. I have been called the 'woman behind the atomic bomb.'

Lise Meitner. Meitner refused to work on the atomic bomb during WWII.

I was born in Massachusetts in 1848 and as an engineer for the U.S. Electric Lighting Company I supervised the installation of street lights in New York City, Philadelphia, Montreal, and London. In 1884 I became the only African-American member of 'Edison's Pioneers.'

Lewis H. Latimer. Latimer wrote the first engineering handbook on lighting systems.

I was born in England in 1818. In 1840 I stated a law, now named after me, that heat is produced in a electrical conductor. I also have an international unit of energy named after me.

James Prescott Joule. Joule also did important work in energy conversation.

I was born in New York in 1819 and drilled the first oil well in Titusville, PA in 1859 using an old steam engine to power the drill. Most historians trace the start of the oil industry to this venture.

Edwin L. Drake. Drake was not a good businessman. He died a poor man in 1876.

I was born in Poland in 1867. My husband and I won the Nobel Prize in physics in 1903 for our discovery of radium. In 1911 I won the Nobel Prize myself in chemistry and thus became the first person to receive the Nobel Prize twice.

Marie Curie. Unfortunately, repeated exposure to radioactive elements lead to Madam Curie's death in 1934.

I was born in England in 1825. By trade a biologist, I was the foremost expounder of Darwinism. I also wrote essays on theology and introduced the term 'agnostic'.

Thomas H. Huxley. Huxley also studied medicine and was a professor of natural history.

I was born in the U.S. in 1912. I was a leading American nuclear chemist. In 1940 I discovered plutonium and worked on the Manhattan Project. In 1951 I shared the Nobel Prize for chemistry.

Glenn Seaborg. Element 106, synthesized in 1974, was named seaborguim in his honor. Seaborg was chairman of the Atomic Energy Commission from 1961 to 1971.

I was born in England in 1749. I investigated the theory that anyone who caught cowpox would be immune to smallpox. I proved the theory correct and developed a vaccination for smallpox.

Edward Jenner. The word vaccination comes from the Latin words 'vacca' for cow and 'vaccinia' for cowpox.
