Our accomplishments never cease to amaze me. Imagine being a scientist who can detect hidden chemicals with just a simple test. Here’s another hidden gem.

Dr. Betty Harris is a brilliant scientist and inventor known for her work in chemistry. She was born on July 29, 1940, in Louisiana. From a young age, Betty was fascinated by science. She loved to learn how things worked and always asked lots of questions. Her passion for science led her to become a chemist.

By 1961, aged just 19, she had graduated from Southern University in Baton Rouge with a chemistry degree.

She did her research at Los Alamos National Laboratory, New Mexico, where she worked in the areas of hazardous waste treatment and environmental remediation as well as explosives chemistry. Areas of focus included explosives detection, synthesis and characterization of insensitive high explosives and sensitivity of weathered high explosives.

Her invention, a spot test for TATB, represents a significant advancement in the detection of this crucial but stable explosive compound.

TATB stands for 1,3,5-triamino-2,4,6-trinitrobenzene. It’s a type of explosive that is very stable and safe to handle, making it important for various safety applications. TATB is used in explosives because it doesn’t explode easily under heat or shock, which means it’s safer to store and use.

Harris invented a special test called a “spot test” to detect TATB. Before her invention, finding TATB in materials was difficult and time-consuming. Her spot test made it quick and easy to detect this important chemical.

The spot test developed by Harris is a simple yet powerful method that involves a few straightforward steps. A small sample of the material in question is obtained. The sample is treated with a special chemical solution formulated by Harris. If TATB is present in the sample, the solution undergoes a color change, providing a clear and immediate indication of its presence.

Harris’s spot test is important for several reasons. The test helps ensure that explosives are safe to handle and store. By detecting TATB quickly, accidents can be prevented. It is easy to use and provides fast results, saving time and resources.

Inventions like Harris’s help science to progress by making it easier to work with important chemicals.

Her contributions extend beyond her scientific achievements. She is a passionate advocate for education and has been a mentor to countless young scientists, particularly encouraging girls and African American students to pursue careers in Science, Technology, Engineering and Math (STEM) fields.

Her dedication to fostering the next generation of scientists has earned her numerous accolades and respect in the academic community.

Harris still lives in New Mexico.

Beverly Lorraine Greene: A Pioneering Architect and Symbol of Possibility and Progress

Greene graduated from the University of Illinois at Urbana-Champaign in 1936 with a degree in Architecture — a remarkable accomplishment for an African American woman at the time. She was never discouraged by the racial and gender discrimination that saturated her field.

In the mid-20th century, Beverly Lorraine Greene was recognized as the first African American woman licensed to practice architecture in the United States.

Greene was born on Oct. 4, 1915, in Chicago during an era when opportunities for African Americans, particularly women, were severely limited.

Her parents, James and Vera Greene, were deeply invested in her education, instilling in her a belief in the power of intellect and perseverance. She grew up during the Great Migration that transformed Chicago starting in 1900.

Greene continued her education, earning a master’s degree in City Planning and Housing in 1937, also from the University of Illinois. Her ambition was not merely to design structures but to shape spaces that fostered equity and community. In 1942, she became the first African American woman licensed as an architect in the United States, obtaining her credentials in Illinois. This groundbreaking achievement, however, did not translate immediately into job opportunities.

Early in her career, she faced significant discrimination from firms unwilling to hire a Black woman. However, her determination never wavered. In 1945, Beverly moved to New York City, a place she believed could offer broader professional opportunities.

She joined the architectural department of the New York City Housing Authority, focusing on affordable housing projects. Her work during this time reflected her commitment to using architecture as a tool for social justice, ensuring that marginalized communities had access to well-designed, dignified living spaces.

Greene’s talents soon drew the attention of prominent firms. She was hired by Isadore Rosenfield, a respected architect known for designing hospitals. She contributed to the design of healthcare facilities, including the modernization of Harlem Hospital. Her portfolio expanded in collaboration with architectural personalities such as Marcel Breuer and Edward Durell Stone.

Notably, she worked on the prestigious UNESCO headquarters in Paris — a landmark project that brought her skills to an international stage. Her involvement underscored her ability to navigate the intricacies of large-scale, global projects, proving that her talents transcended the limitations society sought to impose.

Greene’s career was tragically cut short when she passed away unexpectedly in 1957 at the age of 41. Though her life was brief, her impact was profound. She shattered entrenched barriers, paving the way for future generations of Black architects and women in the field.
