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.

After 10-Year Wait, Fillmore Heritage Center Reopens in San Francisco

After serving as the economic and cultural hub of the Fillmore’s historically Black community for more than a decade, the center’s closure ended what was called the “Rebirth of the Cool,” referring to the neighborhood’s role during the height of Black Jazz in the United States.

Last Saturday morning, the cloudy skies cleared just as the highly anticipated ribbon-cutting ceremony began, marking the reopening of the Fillmore Heritage Center at 1330 Fillmore and Eddy.

The complex – which had once included Yoshi’s Jazz Club, the Lush Life Art Gallery, the Koret Heritage Lobby, a 54-seat microcinema, and the Black-owned 1300 On Fillmore restaurant – shuttered in 2015.

After serving as the economic and cultural hub of the Fillmore’s historically Black community for more than a decade, the center’s closure ended what was called the “Rebirth of the Cool,” referring to the neighborhood’s role during the height of Black Jazz in the United States.

“The Fillmore is the most important neighborhood in San Francisco’s history for centering Black culture, music, business, and community, and has shaped this City and influenced the entire country,” said San Francisco Mayor Daniel Lurie to the gathering of more than 100 community leaders, business owners, and public officials. “This building reflects the deep roots of the Fillmore. Urban renewal left deep scars that are still felt today. This Center celebrates a strong Black community that continues to shape San Francisco. I am proud to join the community as we reopen the Fillmore Heritage Center.”

Although the previous stakeholders will not be returning to the center, spaces are available for nonprofit organizations and ventures, such as Fillmore native Ericka Johnson’s Honey Art Studio.

“This Center will be an economic engine and a thriving venue that shines a light on the Black-owned businesses in this neighborhood and lifts the entire district,” Lurie continued. “Our City is committed to this community for the long term.”

“We’re excited to collaborate with the City to finally reopen these doors,” said Ken Johnson, a videographer and community leader who’d been lobbying for the reopening of the center. “It’s an opportunity to showcase the entrepreneurship and creative spirit of this ‘Harlem of the West’ and the ‘Rebirth of the Cool,’ grounded in our uniquely gifted Fillmore community.”

This month, through its Office of Economic and Workforce Development, the city will begin renting the building’s noncommercial spaces for pop-up events celebrating local talent, arts, and entertainment primarily centered in the Fillmore.

Black Music Month and Juneteenth are inextricably linked – Black music is the sound of our freedom.

From the plaintive moans of the enslaved Africans’ ‘sorrow songs,’ to the fields of Civil War battle where Black soldiers picked up abandoned bugles, to the upright piano played in juke joints on Saturday night and churches come Sunday morning, our ancestors’ innovation in the face of want, fear, degradation, and hopelessness has yielded genres of music imitated ’round the world.

Black Music Month started when Black Music Association members Ed Wright, Kenny Gamble and his wife, journalist and radio host Dyanna Williams were able to persuade President Jimmy Carter to establish the observation on June 7, 1979.

In 2000, Congress made it official. In 2009, Pres. Barack Obama changed the name to African American Music Heritage Month and in 2023, Pres. Joe Biden changed it back to Black Music Month, two years after he declared Juneteenth a national holiday, the result of a movement led by Opal Lee.

Our ancestors battle for freedom over these last 400 years and the music that allowed them expression of their humanity deserved to be honored.

But we may be losing sight of the value of their sacrifices.

‘Sing a Song Full of the Faith That the Dark past Has Taught Us…’

Along with the long-known exploitation of Black musicians whose recordings were stolen by record companies, the commercialization of Juneteenth feels like another kind of theft.

I had never heard of Juneteenth until I moved to the Bay Area from my hometown of Philadelphia. I didn’t know it was one of many freedom festivals celebrated by descendants of enslaved people in the United States.

Emancipation Day was Jan. 1 in Pennsylvania, April 16 in Wash., D.C., May 20 in Florida, and Aug. 8 in Kentucky. But Juneteenth, June 19, has the most renown, known in Texas as the ‘colored peoples’ Fourth of July.’

It was marked by parades, beauty pageants, rodeos, backyard barbecues and church picnics.

Yes, church.

The formerly enslaved began the day praying in thanks for their freedom just as they had prayed for Jubilee – the day of freedom – when they had chains on their feet and hands. They ‘testified’ about their past suffering and how they had managed to overcome.

And they sang.

Although, we will not hold it this year, Omnira Institute’s Juneteenth Ritual of Remembrance recalled this part of Juneteenth with prayers in the languages of the African captives. In the middle of the ceremony, a soloist would lead us in singing “Many Thousand Gone” while we took turns reciting portions of the Emancipation Proclamation, the news of freedom that took more than two years to reach Texas – two months after the Civil War ended.

“Many Thousand Gone” was famously recorded by Black luminary Paul Robeson in 1947:

“No more auction block for me,

No more, no more

No more auction black for me

Many thousand gone.”

Other verses refer to the ‘pint of salt’ and the ‘driver’s lash,’ the realities of enslavement that they had survived.

‘Sing a Song Full of the Hope That the Present has Brought Us’

All of the genres of African American music have at their root songs like that, the essence being, as Stevie Wonder, wrote, “the joy inside our pain.” So Black music is not just music. It is our story, our history, our very strength.

During the Civil Rights Movement, which peaked 100 years after slavery ended, the people testified that it was the freedom songs – based on spirituals – that gave them the heart to march, face attack dogs, fire hoses, beatings, and shootouts with vigilantes.

The music reminded them that power was in the people. That music, our music, can do so again. We don’t have to accept the commodification of the products of our culture.

The power of those songs is showing a resurgence across the South as we battle again for the right to self-determination through the ballot box.

Those songs are the voices of our ancestors, voices forged in their blood, their sweat, their tears, joy and, above all, faith.  Those songs, those prayers live in our blood and our very breath.

This Juneteenth, let us reclaim those holy voices expressed in Black music for ourselves. It is our birthright. It can neither be bought nor sold.  No more. Never again.

Wanda Ravernell is the executive director of Omnira Institute, sponsor for 18 years of the Juneteenth Ritual of Remembrance and Oakland’s 11th Annual Black-Eyed Pea Festival, which will take place on Sept. 12.
