African-American Inventor
This list of African Americans inventors and scientists documents many of the African-Americans who have invented a multitude of items or made discoveries in the course of their lives. These have ranged from practical everyday devices to applications and scientific discoveries in diverse fields, including physics, biology, math, and medicine. African-Americans have been the victims of oppression, discrimination and persecution throughout American history, with an impact on African-American innovation. A 2014 study by economist Lisa D. Cook linked violence towards African-Americans and lack of legal protections over the period 1870–1940 to lower innovation. Despite this, many black innovators have been responsible for a large number of major inventions. Among the earliest was George Washington Carver, whose reputation was based on his research into and promotion of alternative crops to cotton, which aided in nutrition for farm families. He wanted poor farmers to grow alternativ ...

Lonnie Johnson (inventor)
Lonnie George Johnson (born October 6, 1949) is an American inventor, aerospace engineer, and entrepreneur, whose work includes a U.S. Air Force-term of service and a twelve-year stint at NASA, where he worked at the Jet Propulsion Laboratory. He invented the Super Soaker water gun in 1989, which has been among the world's bestselling toys ever since. Early life Johnson was born in Mobile, Alabama. His mother, who finished high school, worked as a nurse's aide and his father, who didn't finish high school, was a World War II veteran. His father explained the basic principles of electricity to Johnson at an early age. Stating that he "always liked to tinker with things," Johnson earned the nickname "the Professor" from kids in the neighborhood. He once tore up his sister's doll to see what made the eyes close. He also tried to cook up rocket fuel in a saucepan but in doing so almost burned down the house. As a teenager, Johnson attended Williamson High School (Alabama), Willia ...

Pittsburgh Post-Gazette
The ''Pittsburgh Post-Gazette'', also known simply as the PG, is the largest newspaper serving metropolitan Pittsburgh, Pennsylvania. Descended from the ''Pittsburgh Gazette'', established in 1786 as the first newspaper published west of the Allegheny Mountains, the paper formed under its present title in 1927 from the consolidation of the ''Pittsburgh Gazette Times'' and ''The Pittsburgh Post''. The ''Post-Gazette'' ended daily print publication in 2018 and has cut down to two print editions per week (Sunday and Thursday), going online-only the rest of the week. In the 2010s, the editorial tone of the paper shifted from liberal to conservative, particularly after the editorial pages of the paper were consolidated in 2018 with '' The Blade'' of Toledo, Ohio. After the consolidation, Keith Burris, the pro-Trump editorial page editor of '' The Blade'', directed the editorial pages of both papers. Early history ''Gazette'' The ''Post-Gazette'' began its history as a four-page w ...

X-ray Spectrometer
X-ray spectroscopy is a general term for several spectroscopic techniques for characterization of materials by using x-ray radiation. Characteristic X-ray spectroscopy When an electron from the inner shell of an atom is excited by the energy of a photon, it moves to a higher energy level. When it returns to the low energy level, the energy which it previously gained by the excitation is emitted as a photon which has a wavelength that is characteristic for the element (there could be several characteristic wavelengths per element). Analysis of the X-ray emission spectrum produces qualitative results about the elemental composition of the specimen. Comparison of the specimen's spectrum with the spectra of samples of known composition produces quantitative results (after some mathematical corrections for absorption, fluorescence and atomic number). Atoms can be excited by a high-energy beam of charged particles such as electrons (in an electron microscope for example), protons (see ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Microbiologist
A microbiologist (from Ancient Greek, Greek ) is a scientist who studies microscopic life forms and processes. This includes study of the growth, interactions and characteristics of Microorganism, microscopic organisms such as bacteria, algae, fungi, and some types of parasites and their vectors. Most microbiologists work in offices and/or research facilities, both in private biotechnology companies and in academia. Most microbiologists specialize in a given topic within microbiology such as bacteriology, parasitology, virology, or immunology. Duties Microbiologists generally work in some way to increase scientific knowledge or to utilise that knowledge in a way that improves outcomes in medicine or some industry. For many microbiologists, this work includes planning and conducting experimental research projects in some kind of laboratory setting. Others may have a more administrative role, supervising scientists and evaluating their results. Microbiologists working in the medi ...

Harold Amos
Harold Amos (September 7, 1918 – February 26, 2003) was an African American microbiologist and professor. He taught at Harvard Medical School for nearly fifty years and was the first African-American department chair of the school. Early life Amos was born in Pennsauken, New Jersey to Howard R. Amos Sr., a Philadelphia postman, and Iola Johnson. Iola Johnson was adopted and educated by a Philadelphia Quaker family. Due to the close relationship between Iola and the Quaker family, the Amos family received a lot of books, including a biography of Louis Pasteur. Excelling as a student, Amos graduated in 1936 at the top of his class from Camden High School in New Jersey. He attended Springfield College in Massachusetts on a full academic scholarship. In 1941 he graduated summa cum laude with a degree in biology(major) and chemistry(minor). He was drafted the following year, and after returning home from WWII in 1946, Amos began his graduate studies at Harvard University. He was the ...
