June 19, or Juneteenth, is independence day for many Americans of African descent.
Also known as Emancipation Day or Freedom Day, it commemorates the end of slavery, the seminal event in Black history.
President Abraham Lincoln’s Emancipation Proclamation took effect on Jan. 1, 1863, but was read to slaves in Galveston, Texas, on June 19, 1865, more than two years later.
There are several different accounts of why the news of freedom took so long to arrive.
One story has it that slaves were intentionally kept ignorant about their freedom in order to allow crops to continue being harvested. Another has a messenger traveling by mule to deliver the news, and it simply took more than two years to arrive from Washington, D.C., to Texas. Yet another story has the messenger being murdered before he could deliver the message.
No matter the origin of Juneteenth, the end of slavery is definitely worth celebrating. But while much has happened in the 158 years since slavery officially ended, its legacies still remain in the form of disparate salaries, educational levels and incarceration rates.
Juneteenth, which is now observed in 48 states (North Dakota and Hawaii do not observe) and the District of Columbia, is a time to take stock of our progress — and of the work that remains.
Last year, during the pandemic our current vice president and former senator, Kamala Harris, said: “[m]y message on this Juneteenth: may we honor those who suffered, died and survived the crushing reality of slavery by looking to the future.”
Twelve years ago President Barack Obama said: “African Americans helped to build our nation brick by brick and have contributed to her growth in every way, even when rights and liberties were denied to them.”
We’re still building it.
In 2021, as our state opens up post-pandemic and we deal with racial reckoning as we never have before #BlackLivesMatter is becoming a reality.
This year is truly our Independence Day.
Happy Juneteenth.

Betty Harris: Inventor of Spot Test That Revolutionized Chemical Detection
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.

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.
