Valerie Thomas (1943 – present) – Illusion transmitter
Valerie Thomas was an African American scientist and inventor who worked for NASA. She is known for inventing the illusion transmitter, which uses two concave mirrors to create three-dimensional images that appear outside the mirrors. Thomas was granted the patent for her invention in 1980, which has been used for various applications (i.e., surgery and television).
Thomas joined NASA in 1964 and worked there for over 30 years. She was involved in developing the Landsat program, which uses satellite imagery to study the Earth’s surface. She was also part of the team that developed the first satellite to provide images of the polar ice caps. Thomas was a trailblazer for women and minorities in science and engineering, and her contributions have impacted the field. She retired from NASA in 1995, but her legacy inspires future scientists and inventors.
