Pioneering NASA Physicist George Alcorn Revolutionized Imaging Technology and STEM Education

Born in Indianapolis in 1940, George Alcorn’s scientific curiosity was sparked early on by his father, an automobile mechanic. “I was a very fortunate boy, in that my hero was my daddy,” George once shared with the National Inventors Hall of Fame®. “I thought that what my father was doing was science.” Together, the pair spent hours tinkering with car engines, setting the stage for Alcorn’s future in STEM.

George Alcorn was a trailblazing physicist and engineer whose groundbreaking inventions transformed aerospace technology and imaging devices. Best known for his creation of the X-ray imaging spectrometer, Alcorn’s work at NASA Goddard Space Flight Center (GSFC) not only advanced space exploration but also reshaped the scientific community’s understanding of deep space phenomena.

Born in Indianapolis in 1940, Alcorn’s scientific curiosity was sparked early on by his father, an automobile mechanic. “I was a very fortunate boy, in that my hero was my daddy,” George once shared with the National Inventors Hall of Fame®. “I thought that what my father was doing was science.” Together, the pair spent hours tinkering with car engines, setting the stage for Alcorn’s future in STEM.

That foundation propelled him through an impressive academic journey. After earning a bachelor’s degree in physics from Occidental College in 1962, he pursued graduate studies at Howard University, where he received a master’s degree in 1963 and a doctorate in atomic and molecular physics in 1967.

Alcorn began his career in private industry, working at IBM on high-performance semiconductor devices. In 1978, he joined NASA GSFC, where his contributions revolutionized imaging technology and space exploration.

In 1982, he invented the X-ray imaging spectrometer, a device that allowed scientists to more accurately detect and analyze elemental and chemical components. The innovation earned him the title of 1984 NASA GSFC Inventor of the Year. This spectrometer has since been used in planetary mapping, star charting, and deep space exploration, and its descendants continue to shape modern imaging technologies.

Beyond his spectrometer, Alcorn contributed to the development of the Freedom Space Station in collaboration with international agencies and invented the Airborne LIDAR Topographic Mapping System (ALTMS). ALTMS uses light to analyze Earth’s surface and has become integral to data collection for environmental studies and drone technology. 

Alongside his technical achievements, Alcorn was a passionate educator. He taught physics and engineering at Howard University and mentored underrepresented doctoral candidates at the University of the District of Columbia. Recognizing the importance of engaging students early, he co-founded the Saturday Academy, a weekend program aimed at inspiring inner-city middle schoolers in Washington, D.C., to develop an interest in math and science.

“I believe it’s so important to start learning and enjoying learning as young as possible,” Alcorn said. “It gives children even more of an advantage.”

Alcorn’s contributions earned him numerous accolades, including the prestigious Robert H. Goddard Award of Merit from NASA GSFC in 2010 and the Alumni Seal Award for Professional Achievement from Occidental College in 2012.

Reflecting on his work, Alcorn remarked, “If you have a good, interesting project, work is not coming to work – it’s coming to an adventure.”

Post Newspaper Invites NNPA to Join Nationwide Probate Reform Initiative

The Post’s Probate Reform Group meets the first Thursday of every month via Zoom and invites the public to attend.  The Post is making the initiative national and will submit information from its monthly meeting to the NNPA to educate, advocate, and inform its readers.

The National Newspaper Publishers Association (NNPA) represents the Black press with over 200 newspapers nationwide.

Last night the Post announced that it is actively recruiting the Black press to inform the public that there is a probate “five-alarm fire” occurring in Black communities and invited every Black newspaper starting from the Birmingham Times in Alabama to the Milwaukee Times Weekly in Wisconsin, to join the Post in our “Year of Action” for probate reform.

The Post’s Probate Reform Group meets the first Thursday of every month via Zoom and invites the public to attend.  The Post is making the initiative national and will submit information from its monthly meeting to the NNPA to educate, advocate, and inform its readers.

Reporter Tanya Dennis says, “The adage that ‘When America catches a cold, Black folks catch the flu” is too true in practice; that’s why we’re engaging the Black Press to not only warn, but educate the Black community regarding the criminal actions we see in probate court: Thousands are losing generational wealth to strangers. It’s a travesty that happens daily.”

Venus Gist, a co-host of the reform group, states, “ Unfortunately, people are their own worst enemy when it comes to speaking with loved ones regarding their demise. It’s an uncomfortable subject that most avoid, but they do so at their peril. The courts rely on dissention between family members, so I encourage not only a will and trust [be created] but also videotape the reading of your documents so you can show you’re of sound mind.”

In better times, drafting a will was enough; then a trust was an added requirement to ‘iron-clad’ documents and to assure easy transference of wealth.

No longer.

As the courts became underfunded in the last 20 years, predatory behavior emerged to the extent that criminality is now occurring at alarming rates with no oversight, with courts isolating the conserved, and, I’ve  heard, many times killing conservatees for profit. Plundering the assets of estates until beneficiaries are penniless is also common.”

Post Newspaper Publisher Paul Cobb says, “The simple solution is to avoid probate at all costs.  If beneficiaries can’t agree, hire a private mediator and attorney to work things out.  The moment you walk into court, you are vulnerable to the whims of the court.  Your will and trust mean nothing.”

Zakiya Jendayi, a co-host of the Probate Reform Group and a victim herself, says, “In my case, the will and trust were clear that I am the beneficiary of the estate, but the opposing attorney said I used undue influence to make myself beneficiary. He said that without proof, and the judge upheld the attorney’s baseless assertion.  In court, the will and trust is easily discounted.”

The Black press reaches out to 47 million Black Americans with one voice.  The power of the press has never been so important as it is now in this national movement to save Black generational wealth from predatory attorneys, guardians and judges.

The next probate reform meeting is on March 5, from 7 – 9 p.m. PST.  Zoom Details:
Meeting ID: 825 0367 1750
Passcode: 475480

All are welcome.

Dorothy Lee Bolden: Uniting Domestic Workers

Domestic work followed Bolden beyond high school. According to sources from the New York Times, Bolden said she would wake “at 4 a.m. to leave home by 6 a.m., and be on the job by 8 a.m., perform all those duties necessary to the proper management of a household for eight hours, leave there by 4 p.m. to be home by 6 p.m. where I would do the same things I’ve done all over again for my own family.”

Her first experience with domestic work was at the age of nine. For $1.25 per week, Alabama-born Dorothy Lee Bolden (1923–2005), alongside her mother, washed soiled diapers for a White employer. Little did anyone know that this profession would spur Bolden to spearhead the movement for basic dignity and respect for generations of domestic workers.

Domestic work followed Bolden beyond high school. According to sources from the New York Times, Bolden said she would wake “at 4 a.m. to leave home by 6 a.m., and be on the job by 8 a.m., perform all those duties necessary to the proper management of a household for eight hours, leave there by 4 p.m. to be home by 6 p.m. where I would do the same things I’ve done all over again for my own family.”

It was Bolden’s experiences working as a domestic in 1940’s Atlanta that inspired her civil rights activism. A White female employer demanded that Bolden remain beyond her shift and wash dishes. Bolden refused. She was arrested and held in a county jail because “she was crazy.” There was no other reason for disobeying an order from a White person.

Bolden was never sentenced or institutionalized, but this event was the seed that grew into organization that would protect domestic workers across the United States: the National Domestic Workers Union of America.

Rosa Parks had made public transportation a major breeding ground for civil rights activism, so Bolden began organizing during the long bus rides her peers made to the wealthy neighborhoods. Many were fed up, working long hours for little pay, with little to no worker protections.

This organization of women would go on to fight for worker’s rights, create training programs, and teach workers to advocate for themselves. It was also important to Bolden to teach communication skills.

In the book Household Workers Unite, Bolden is quoted as saying: “You have to teach each maid how to negotiate… And this is the most important thing — communication. I would tell them it was up to them to communicate.”

But respect for Bolden’s activism was not shared by everyone. Although she consulted presidents Ford, Reagan, and Carter, she received several death threats from the Ku Klux Klan.

The New York Times reported that during the makings of an oral history project, Bolden said that “men claiming to be members of the KKK called her house and spoke about “whipping my behind,” but in coarser terms. “I told them any time they wanted to, come on over and grab it,” Bolden said during the interview. “It didn’t scare me, didn’t bother me. It made me angry. It made me determined to do what I had to do.”

Representative John Lewis of Georgia said that Bolden “spoke up, and she spoke out, and when she saw something that wasn’t fair, or just, or right, she would say something.”

The NDWU of America ran until the mid-1990s, but Bolden’s legacy lives on.

Book Review: Books on Black History and Black Life for Kids

For the youngest reader, “As You Are: A Hope for Black Sons” by Kimberly A. Gordon Biddle, illustrated by David Wilkerson (Magination Press, $18.99) is a book for young Black boys and for their mothers. It’s a hope inside a prayer that the world treats a child gently, and it could make a great baby shower gift.

Authors: Various, Copyright: c. 2025, 2026, Publishers: Various, SRPs: $17.99-$18.99, Page Counts: Various, 

Everybody in your family has stories to share.

Your parents have told you some, no doubt. Your grandparents have offered a few, too, and aunties and uncles have spun some good tales. But there’s so much more to know, so grab one of these great books and learn about Black History and Black life.

For the youngest reader, “As You Are: A Hope for Black Sons” by Kimberly A. Gordon Biddle, illustrated by David Wilkerson (Magination Press, $18.99) is a book for young Black boys and for their mothers. It’s a hope inside a prayer that the world treats a child gently, and it could make a great baby shower gift.

If someone said you couldn’t do something that you were clearly able to do, would you fight to do it anyhow?  In the new book, “Remember Her Name! Debbie Allen’s Rise to Fame” by Tami Charles, illustrated by Meredith Lucius (Charlesbridge, $17.99), a young girl in the Jim Crow South is told that she can’t dance because of the color of her skin.

She didn’t listen, though, and neither did her mother, who took her daughter to Mexico, where the girl soared! This is an inspiration for any 5-to-7-year-old; be sure to check out the back-of-the-book information, if you’re an adult fan.

Do you often hear your elders say things that sound like lessons?  They might be, so “Where There is Love: A Story of African Proverbs” by Shauntay Grant, illustrated by Leticia Moreno (Penguin Workshop, $18.99) is a book you’ll like. It’s a quick-to-read collection of short proverbs that you can say every day. Kids ages 4-to-6 will easily remember what they find in this book; again, look in the back for more information.

Surely, you love your neighborhood, which is why the tale inside “Main Street: A Community Story about Redlining” by Britt Hawthorne and Tiffany Jewell, illustrated by David Wilkerson (Penguin Kokila, $18.99) is a book for you.

Olivia’s neighborhood is having a block party, but she’s sad when no one shows up. That’s when she learns that “the government” is discriminating against the people and businesses near where she lives. So, what can she and her neighbors do? The answer might inspire 6-to-8-year-old kids to stand up to wrongs they see, and to help make their neighborhoods stronger and safer.

And finally, if a kid wants a book, where can they go to find it? In “I’m So Happy You’re Here: A Celebration of Library Joy” by Mychal Threets, illustrated by Lorraine Nam (Random House, $18.99) is a good introduction to the best of what a library has to offer. The freedom to walk into a library and borrow a book is the theme here, as is the sheer happiness of being welcomed, no matter who you are.  This is an easy book for kids as young as two and as old as five to enjoy.

On that note, if you want more, head to that library, or a nearby bookstore. They’ll be glad to see you. They’ve got stories to share.
