George Edward Alcorn Jr. was born on March 22, 1940, in Indianapolis.
Growing up in a family that valued education, Alcorn developed an early love for science and mathematics. He excelled in school, and attended Occidental College in California, where he earned a bachelor’s degree in physics in 1962. He received a master’s degree in nuclear physics in 1963 and a Ph.D. in atomic and molecular physics in 1967 at Howard University.
Alcorn began his career in developing scientific technology in private industries, starting a career as a physicist for IBM. His career took off when he joined several prestigious companies and research institutions, such as the Aerospace Corporation, where he developed important technologies for spacecraft. In 1978, he accepted a position at NASA’s Goddard Space Flight Center, where he worked for the remainder of his career. There, he developed technologies for space stations and private institutions across the nation, becoming a key figure in the field of physics and space exploration.
Alcorn is well known for his groundbreaking work on X-ray spectrometers. An X-ray spectrometer is a device used to identify different elements in materials by analyzing the X-ray wavelengths they emit. His improvements allowed the instrument to detect X-rays with greater accuracy and efficiency. This invention has been critical for NASA’s space missions, aiding in the analysis of planetary atmospheres and surfaces, including Mars and other planets in our solar system.
He also contributed to the development of plasma etching, a process used in manufacturing microchips for computers and electronics. His work in this area advanced semiconductor technology, which powers everything from smartphones to satellites.
Another accomplishment was the development of new technologies used in the Freedom space station in partnership with space agencies in Japan, Canada and Europe, though their projects never made it to space.
Throughout his career, Alcorn received several awards and honors, including NASA’s Inventor of the Year Award in 1984. In 2010, he received the highest honor from NASA’s Goddard Space Flight Center. In 2015, Alcorn was inducted into the National Inventors Hall of Fame for his invention of the imaging X-ray spectrometer.
In addition to his work in the lab, Alcorn dedicated much of his time to teaching and mentoring young scientists. As one of the few African American scientists working in advanced fields like physics and space exploration, he has been an inspiration to young people, especially those from underrepresented groups in STEM (science, technology, engineering, and mathematics). He taught at Howard University and worked to encourage more African Americans to pursue careers in science and engineering.
George is quoted as stating, “The big thing about being in science and engineering is that if you have a good, interesting project going, work is not coming to work, it’s coming to an adventure.”
George Edward Alcorn passed away June 19, 2024.

OPINION: Your Voice and Vote Impact the Quality of Your Health Care
One of the most dangerous developments we’re seeing now? Deep federal cuts are being proposed to Medicaid, the life-saving health insurance program that covers nearly 80 million lower-income individuals nationwide. That is approximately 15 million Californians and about 1 million of the state’s nearly 3 million Black Californians who are at risk of losing their healthcare.

Shortly after last year’s election, I hopped into a Lyft and struck up a conversation with the driver. As we talked, the topic inevitably turned to politics. He confidently told me that he didn’t vote — not because he supported Donald Trump, but because he didn’t like Kamala Harris’ résumé. When I asked what exactly he didn’t like, he couldn’t specifically articulate his dislike or point to anything specific. In his words, he “just didn’t like her résumé.”
That moment really hit hard for me. As a Black woman, I’ve lived through enough election cycles to recognize how often uncertainty, misinformation, or political apathy keep people from voting, especially Black voters whose voices are historically left out of the conversation and whose health, economic security, and opportunities are directly impacted by the individual elected to office, and the legislative branches and political parties that push forth their agenda.
That conversation with the Lyft driver reflects a troubling surge in fear-driven politics across our country. We’ve seen White House executive orders gut federal programs meant to help our most vulnerable populations and policies that systematically exclude or harm Black and underserved communities.
One of the most dangerous developments we’re seeing now? Deep federal cuts are being proposed to Medicaid, the life-saving health insurance program that covers nearly 80 million lower-income individuals nationwide. That is approximately 15 million Californians and about 1 million of the state’s nearly 3 million Black Californians who are at risk of losing their healthcare.
Medicaid, called Medi-Cal in California, doesn’t just cover care. It protects individuals and families from medical debt, keeps rural hospitals open, creates jobs, and helps our communities thrive. Simply put; Medicaid is a lifeline for 1 in 5 Black Americans. For many, it’s the only thing standing between them and a medical emergency they can’t afford, especially with the skyrocketing costs of health care. The proposed cuts mean up to 7.2 million Black Americans could lose their healthcare coverage, making it harder for them to receive timely, life-saving care. Cuts to Medicaid would also result in fewer prenatal visits, delayed cancer screenings, unfilled prescriptions, and closures of community clinics. When healthcare is inaccessible or unaffordable, it doesn’t just harm individuals, it weakens entire communities and widens inequities.
The reality is Black Americans already face disproportionately higher rates of poorer health outcomes. Our life expectancy is nearly five years shorter in comparison to White Americans. Black pregnant people are 3.6 times more likely to die during pregnancy or postpartum than their white counterparts.
These policies don’t happen in a vacuum. They are determined by who holds power and who shows up to vote. Showing up amplifies our voices. Taking action and exercising our right to vote is how we express our power.
I urge you to start today. Call your representatives, on both sides of the aisle, and demand they protect Medicaid (Medi-Cal), the Affordable Care Act (Covered CA), and access to food assistance programs, maternal health resources, mental health services, and protect our basic freedoms and human rights. Stay informed, talk to your neighbors and register to vote.

IN MEMORIAM: Nate Holden, State Senator and Longtime Los Angeles Councilmember, Dies at 95
Los Angeles County Supervisor Janice Hahn described Holden as “a lion” in the State Senate and a force to be reckoned with on the Los Angeles City Council.” Hahn added that she learned a lot working with Holden when she was a new councilmember.

Former Los Angeles City Councilmember Nathaniel “Nate” Holden, a prominent figure in the city’s politics, passed away at the age of 95, his family confirmed on May 7.
Holden, who represented South Los Angeles for 16 years on the City Council and served one term in the California State Senate, was widely regarded as a forceful advocate for his community.
Los Angeles County Supervisor Janice Hahn described Holden as “a lion” in the State Senate and a force to be reckoned with on the Los Angeles City Council.”
Hahn added that she learned a lot working with Holden when she was a new councilmember.
Holden’s journey to political prominence began in the segregated South, where he was born in Macon, Georgia, in 1929. He often recalled the childhood moment when he first heard the governor of Georgia vowing to continue suppressing Black people.
“Doing the best you can for the people. Law and order. Make sure that people’s communities are safe. I did it all,” said Holden, reflecting on his legacy.
Holden is survived by his sons, including former California Assemblymember Chris Holden, who represented a district in Southern California that includes Pasadena and Altadena in Los Angeles County and cities in San Bernardino County.

Henry Blair, the Second African American to Obtain a Patent
Being a successful farmer required consistent production. Blair figured out a way to increase his harvest. He did this with two inventions. His first invention was a corn planter. The planter had the same structure as a wheelbarrow, with a box to hold the seed and rakes dragging behind to cover them. This machine allowed farmers to plant their crops more economically.

The debate over whether enslaved African Americans could receive U.S. Government-issued patents was still unfolding when the second African American to hold a patent, Henry Blair, received his first patent in 1834.
The first African American to receive a patent was Thomas Jennings in 1821 for his discovery of a process called dry scouring, also known as dry cleaning.
Blair was born in Glen Ross, Maryland, in 1807. He was an African American farmer who received two patents. Each patent was designed to help increase agricultural productivity.
There is very little information about his life prior to the inventions. It is known that he was a farmer who invented machines to help with planting and harvesting crops. There is no written evidence that he was a slave.
However, it is apparent that he was a businessman.

The planter had the same structure as a wheelbarrow, with a box to hold the seed and rakes dragging behind to cover them. This machine allowed farmers to plant their crops more economically.
Blair could not write. As a result of his illiteracy, he signed the patent with an “X”. He received his first patent for the corn planter on Oct. 14, 1834.
Two years later, taking advantage of the boost in the cotton industry, he received his second patent. This time for a cotton planter. This machine worked by splitting the ground with two shovel-like blades that were pulled along by a horse. A wheel-driven cylinder behind the blades placed seeds into the freshly plowed ground. Not only was this another economical and efficient machine. It also helped with controlling weeds and put the seeds in the ground quickly Henry Blair received his second patent on Aug. 31, 1836
During this time, the United States government passed a law that allowed patents to be granted to both free and enslaved men. However, in 1857, this law was contested by a slaveowner. He argued that slaveowners had a right to claim credit for a slave’s inventions. His argument was that since an owner’s slaves were his property, anything that a slave owned was the property of the owner also.
In 1858 the law changed, and patents were no longer given to slaves. However, the law changed again in 1871 after the Civil War. The patent law was revised to permit all American men, regardless of race, the right to patent their inventions.
Blair died in 1860.
