Until the 1880s only rich people could afford good shoes. It was made mainly by hand, the most difficult thing was to attach the sole to the top of the shoe. Only a highly skilled worker who produced about 50 pairs a day could do that. Jan Matseliger, a young immigrant from South America with a talent for mechanics, developed a machine that did the job much faster. His invention could produce up to 700 pairs of shoes a day. As a result, shoes are much cheaper. In 1991, Matseliger was represented on United States postage stamps.
“Never agree to less than your best” Patricia BathHer parents told her. She never did. A doctor, scientist, inventor and educator, Bath had a number of “firsts” in her career. She is best known for her work to prevent blindness among people who do not have proper medical care. In 1981, she developed a new method of using a laser to remove cataracts (pronounced CAT-uh-racts), clouding the lens of the eye. Its method, used worldwide, is credited with helping to restore or improve the eyesight of millions of people.
When George Carruthers built his first telescope in 10 years, he couldn’t have known he would ever have a telescope on the moon. Decades later, he led a team that developed a sophisticated camera / telescope that went to the moon during the 1972 Apollo 16 mission. The 50-pound device peeked into space, giving photos of the Earth’s outer atmosphere, several stars and distant galaxies. Carruthers also created instruments for the Skylab space station and space shuttle programs.
The school summer program has started Sandra K. Johnsoncareer as an electrical engineer. Her first job was at IBM, a giant global technology company. She worked to increase the speed of the computer and helped develop an early version of IBM’s chess computer “Deep Blue”. His ability to handle complex computing has advanced the field of computer science. After working as IBM’s Chief Technology Officer in Central, East and West Africa, Johnson set up his own company in 2018. Its goal is to use technology to improve the lives of people in sub-Saharan Africa.
I just couldn’t finish primary school Gareth Morgan back. His inventions included a “protective hood” respirator – an early type of gas mask – to protect firefighters and workers exposed to hazardous substances. In 1923, witnessing a traffic accident, he created a traffic light signal with moving arms to signal the driver to stop or drive. Morgan also developed hair care products, including a straightening fluid, which he tested in neighboring Airedale. The liquid straightened the dog’s fur so much that its owner allegedly did not recognize it afterwards.
Mathematics led Gladys West from her childhood farm 100 miles north to the United States Navy facility, where she did sophisticated calculations and programmed computers for four decades before retiring in 1998. She led teams on groundbreaking satellite projects to monitor the world’s oceans and create a detailed model of the Earth’s surface, a section of science called geodesy (gee-ODD-es-see). Her work became the basis for the Global Positioning System (GPS). Satellite display systems are used worldwide, but not in the West. She prefers paper cards.
