Mark Dean was born on March 2, 1957. Dean has a passion for construction from a young age. Dean's father, a manager at the Tennessee Valley Authority, assisted him as a young boy in building a tractor from scratch. Dean was a multifaceted success who stood out as a skilled athlete, a brilliant student, and a straight-A graduate from Jefferson City High School. At the University of Tennessee, where he studied engineering, he graduated first in his class in 1979. He continued his breakthrough work after that, nevertheless. The accessibility and power of the personal computer were changed as a result of Dean's research at IBM. His efforts contributed to the creation of the color personal computer monitor, and in 1999 Dean oversaw a group of engineers at IBM's Austin, Texas, lab to produce the first gigahertz chip, a ground-breaking invention that can perform a billion calculations per second.

Gladys West was bron on October 27, 1930. In school Gladys West always had her aptitude for learning opened her a different route. Gladys gained a full scholarship to Virginia State College (now Virginia State University), a historically Black college, as the class valedictorian of her high school, where she majored in mathematics and graduated in 1952. From West's work on Seasat, the satellite GEOSAT was developed, which is designed to represent the surface of the Earth in virtual reality. A program that could correctly calculate satellite orbits was developed by West and her colleagues by teaching a computer to take into account gravity, tides, and other factors that operate on the surface of the Earth. The GPS system can produce precise calculations of any location on Earth thanks to this model and subsequent modifications.

The first computer software programmer was Margaret Hamilton, née Margaret Heafield, who was born in Paoli, Indiana, on August 17, 1936. She coined the phrase "software engineer" to define her line of work. In the late 1960s and early 1970s, she contributed to the creation of the computer code for the command and lunar modules used on the Apollo missions to the Moon. She met James Hamilton at Earlham College in Richmond, Indiana, where she was majoring in philosophy and mathematics. The two eventually got married. She briefly taught high school mathematics after earning her degree in 1958. Later, the couple relocated to Boston. While her husband attended Harvard Law, Margaret got a position at the Massachusetts Institute of Technology (MIT), despite her plans to study abstract mathematics at Brandeis University.
