Black History Month–Day 10

In honor of Black History Month, here are few profiles of contributors to history of African descent:

Marc Hannah

Anyone awed by the special effects in the films Jurassic Park, Terminator 2 and The Abyss should thank Hannah. The computer scientist is one of the founders, in 1982, of the software firm Silicon Graphics (now SGI), where the special-effects genius developed 3-D graphics technology that would be used in many Hollywood movies. Donkey Kong fans also owe a debt of gratitude to Hannah: He was instrumental in designing the Nintendo 64 gaming system.

Kenneth J. Dunkley

3-D Viewing Glasses and Holography

Kenneth J. Dunkley is currently the president of the Holospace Laboratories Inc. in Camp Hill, Pennsylvania. He is best known for inventing Three Dimensional Viewing Glasses (3-DVG) – his patented invention that displays 3-D effects from regular 2-D photos without any type of lenses, mirrors or optical elements. By studying human vision, Dunkley discovered that blocking two points in a person’s peripheral vision will cause an ordinary picture to appear 3-Dimensional, so he developed his 3-DVG to block out these points.
In addition to his 3-DVG invention, Kenneth Dunkley also receives attention for his efforts as a visual pioneer. In Harrisburg, PA, at the Museum of Scientific Discovery, he has conducted visual effects workshops for four years. Dunkley is also a leader in the field of holography.

Black History Month–Day 9

In honor of Black History Month, here are few profiles of contributors to history of African descent:

Gerald A. Lawson

Anyone who owns a Playstation, Wii or Xbox should know Lawson’s name. He created the first home video game system that used interchangeable cartridges, offering gamers a chance to play a variety of games and giving video game makers a way to earn profits by selling individual games, a business model that exists today. Lawson, who died last year at age 70, is just beginning to be recognized by the gaming industry for his pioneering work. Continue reading

Black History Month–Day 8

In honor of Black History Month, here are few profiles of contributors to history of African descent:

Garrett Morgan

(1873-1963), In 1914 a Black inventor named Garrett Morgan invented the gas mask.  It was used by many rescue agencies to save many lives.  Also during World War 1, the gas mask was very important in protecting american solders from poison gas attacks.  He also invented the traffic lights that we use today.

Norbert Rillieux


(1806-1894), Norbert Rillieux was a Black inventor who invented the multiple effect vaccum pan evaporator.  This device improved the quality of sugar.  Rillieux’s work still impacts the sugar industry and the manufacture of soap, glue, condensed milk and other products.  Charles A. Brown, a chemist with the U.S. Department of Agriculture, described Rillieux’s invention as “the greatest in the history of American chemical engineering.”  Rillieux also developed a plan for a sewer system for New Orleans that would have greatly improved the health conditions there.  The city government rejected the plan because he was black.

Black History Month–Day 7

In honor of Black History Month, here are few profiles of contributors to history of African descent:

First Lt. Vernon J. Baker

Extraordinary Heroism (Medal of Honor)

He received a Medal of Honor for his extraordinary heroism in action near Viareggio, Italy, during World War II. Then holding the rank of second lieutenant, Baker demonstrated outstanding courage and leadership in destroying enemy installations, personnel and equipment during his company’s attack against a strongly entrenched enemy in mountainous terrain. The federal government later acknowledged that racism was the reason he didn’t receive the medal until 50 years later.

George Crum

Inventor of Potato Chips

Every time a person crunches into a potato chip, he or she is enjoying the delicious taste of one of the world’s most famous snacks – a treat that might not exist without the contribution of black inventor George Crum.
The son of an African-American father and a Native American mother, Crum was working as the chef in the summer of 1853 when he incidentally invented the chip. It all began when a patron who ordered a plate of French-fried potatoes sent them back to Crum’s kitchen because he felt they were too thick and soft.
To teach the picky patron a lesson, Crum sliced a new batch of potatoes as thin as he possibly could, and then fried them until they were hard and crunchy. Finally, to top them off, he added a generous heaping of salt. To Crum’s surprise, the dish ended up being a hit with the patron and a new snack was born!

Black History Month–Day 6

In honor of Black History Month, here are few profiles of contributors to history of African descent:

George Washington Carver

Inventor of Over 300 Peanut Products

George Washington CarverGenerally, when people think of famous African-American inventors, one of the first names that springs to mind is George Washington Carver. Perhaps most famously, Carver’s inventions included the discovery of over 300 different uses for peanuts – such as making cooking oil, axle grease and printer’s ink. But despite his penchant for inventing, Carver was never interested in money or prestige so much as helping his fellow man.

Born at the end of the civil war, George Washington Carver displayed a strong desire for knowledge from an early age and took particular interest in plants. As a young boy, Carver became known as the “plant doctor” and was regularly called upon by neighbors to “cure” ailing plants. But it wasn’t until late in his twenties that Carver had the opportunity to study plants more thoroughly. While initially enrolled at Simpson College to study art and piano, Carver transferred to Iowa State College of Agriculture and Mechanic Arts (now known simply as Iowa State University) to follow his passion.
