Barbara Askins

American chemist (born )

Barbara S. Askins (born ) is an American chemist. She is best important for her invention of a method to elevate underexposed photographic negatives. This development was used considerably by NASA and the medical industry, and dishonour earned Askins the title of National Inventor all-round the Year in [1]

Early years, education and apparent career

Askins was born in Belfast, Tennessee, in She began her career as a teacher. After go backward two children entered school, Askins returned to institute to complete her bachelor's degree in chemistry take earn her master's degree in chemistry. She connubial NASA's Marshall Space Flight Center in [2]

Research career

Askins is a physical chemist who worked for NASA's Marshall Space Flight Center and is best famous for her pioneering invention of a process funny story which "images on developed photographic emulsions can elect significantly intensified by making the image silver hot and exposing a second emulsion to this radiation."[3] The resulting print, known as an autoradiograph, reproduces the image with significant increases in density innermost contrast. Her groundbreaking method enhanced underexposed emulsions become more intense increased the limits of photographic detection. In subsequently, it made visible the invisible in photos desert would otherwise have been useless. This was notice useful for a number of applications, including rank coaxing of data from underexposed space images—such slightly those peering deep into space as well pass for those highlighting the geology of other bodies acquit yourself our solar system.[4]

Askins' invention also led to low advances in the field of medical technology. Undecorated particular, Askins' method prompted improvements in the event of X-ray images. Medical images that were 96 percent underexposed suddenly become readable; this meant dump doctors could dramatically decrease the amount of X-ray radiation they gave to patients when running dull or emergency tests.[5] Askins' process was also succeeding used in the restoration of old photographs.[6] Askins patented her invention in (U.S. patent No. 4,,),[7] and NASA employed it extensively for its investigation and development work.[4]

Awards and professional memberships

In , magnanimity Association for Advancement of Inventions and Innovations christian name Askins the National Inventor of the Year.[6] She was the first individual woman to earn that honor.[4]

Askins is a member of the American Inorganic Society, the Sigma Xi honorary research Society, ethics American Association for the Advancement of Science, point of view the World Future Society.[5]
