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.”

IN MEMORIAM: Marcia Ann Gillespie, Editor of Essence and Ms. Magazines, Dies at 82

Marcia Ann Gillespie, the trailblazing journalist who served as the first editor-in-chief of Essence magazine, has died at age 82. After joining the publication at its inception in 1970, Gillespie spent a decade elevating the beauty and voices of Black women during a pivotal era of self-love and cultural revolution. She later broke barriers as the first Black woman to lead Ms. magazine, further solidifying her status as a titan of the publishing industry. Her expansive career also included authorship and teaching, leaving a profound impact on American media. Read more.

Marcia Anna Gillespie, the first editor in chief of Essence magazine, has died. She was 82.

Born in Rockville Centre, New York, in 1944. The daughter of a church sexton/small business owner and domestic worker/caterer, Gillespie parlayed her degree in American studies from Illinois’s Lake Forest College into a research job at Time-Life Books, Inc. in New York.

There she advocated for fairness and inclusion of Black life in its publications. When the owners of the standard bearer of Black life, Ebony magazine, ventured into creating a special publication for young, Black women, Gillespie was hired as managing editor in 1970, and became editor-in-chief a year later at the young age of 26.

At the time, the venture by the Johnson family – the owners of Ebony magazine and Jet – into creating a publication for young Black women met the growing revolution of self-love in the Black community.

In other words, the battle cry of the late 1960s, “Black is Beautiful,” had a place to be seen and not just heard.

Thousands of young women who had already abandoned straightening combs and European aesthetics learned more ways to wear their natural hair from Afros to cornrows. Young Black designers got a place in the spotlight not just in clothing but jewelry that expressed neo-African ideals. But one of the most important impacts was the magazine’s unapologetic elevation of the beauty of the dark-skinned Black female to the status she deserved.

Under Gillepie’s tenure, Essence championed storytelling that celebrated Black women’s identities, experiences, and contributions at a time when their voices were often overlooked in mainstream media,” Essence wrote in a statement posted to Instagram

For 10 years she steered the fledgling publication before joining Ms. Magazine as a contributor in 1980 later becoming the first Black woman to edit a mainstream American magazine when she took charge in 1992.

In 1998, she helped secure the publication’s future through a women-led ownership group. She stayed at Ms. In various capacities until 2001, during which time the magazine had the most diverse readership in its history.

She also mentored future Essence editor Susan L. Taylor and taught young journalists at SUNY Old Westbury.

Emmy-winning actor Sheryl Lee Ralph took to social media to honor Gillespie’s life. 

“Rest in peace, dear Marcia Gillespie,” she wrote on Threads. “Your voice, your brilliance, and your commitment to lifting up Black women leaves a legacy that will continue to inspire me and so many others.”

A professor at SUNY Old Westbury and Bennett College, she also co-authored the authorized biography “Maya Angelou: A Glorious Celebration” in 2008.

According to Wikipedia, she also served on various boards as a director or advisor, including: “…the Arthur Ashe Institute of Urban Health, the Black & Jewish Women of New York, the Violence Policy Center in Washington, D.C., Aspen Institute, …and the Studio Museum of Harlem. Gillespie is a member of the National Council of Negro Women and the American Association of Magazine Editors.”

She was the recipient of several awards, including: the Lake Forest College Outstanding Alumni Award (1973), the New York Women in Communications Matrix Award (1978); a Lifetime Achievement Award from the New York Association of Black Journalists for print journalism (1982); a ‘Top Ten Outstanding Women in Magazine Publishing’ recognition by the March of Dimes.

In later years she was inducted into the American Society of Magazine Editors’ Hall of Fame (2002); the NAACP President’s Award (2006) and the Barbara Graves Legacy Award at the Black Enterprise Women of Power Summit in 2017.

The conclusion for her online obituary reads: “She leaves behind a legacy written not just in the pages she edited, but in every editor, journalist, and reader who found themselves — finally — in the stories she chose to tell.”

Online sources for this report include “The History Makers,” The Washington Informer, Wikipedia, Essence magazine, Ms. Magazine and her obituary.

HISTORY MADE: Keisha Lance Bottoms Becomes First Black Woman Elected Governor in American History

ATLANTA DAILY WORLD — History has been made in Georgia. Keisha Lance Bottoms, the former mayor of Atlanta, has been elected governor of Georgia, becoming the first Black woman in American history to win the highest executive office in any state.

History has been made in Georgia. Keisha Lance Bottoms, the former mayor of Atlanta, has been elected governor of Georgia, becoming the first Black woman in American history to win the highest executive office in any state.

Bottoms’ victory over Republican businessman Rick Jackson represents a defining moment in American politics, breaking a barrier that has stood since the nation’s founding and placing Georgia at the center of a historic political transformation.

For generations, Black women have played a critical role in American democracy, organizing communities, leading movements, mobilizing voters and shaping public policy. Yet despite their contributions, no Black woman had ever been elected governor of a U.S. state.

Until now.

Bottoms’ election also makes her the first woman and first Black person elected governor of Georgia, a state whose political history has been deeply shaped by slavery, segregation, the civil rights movement and the long struggle for equal representation.

Her victory carries particular significance in a state where Black women have been among the most influential forces in voter registration, political organizing and Democratic electoral success.

A fifth-generation Georgian, Bottoms previously served as Atlanta’s 60th mayor from 2018 to 2022. During her administration, she led the city through the COVID-19 pandemic, nationwide protests over racial injustice and a period of significant economic and population growth.

Following her time as mayor, Bottoms served as a senior adviser in President Joe Biden’s administration before returning to Georgia politics to pursue the governorship.

Her campaign focused on expanding access to health care, strengthening public education, increasing wages and addressing the rising cost of living. She also advocated for expanding Medicaid, raising Georgia’s minimum wage to $15 an hour and increasing compensation for teachers and other public employees.

Bottoms faced Jackson, a wealthy health care executive who invested heavily in his campaign and positioned himself as a political outsider. The contest drew national attention as Democrats sought to reclaim the Georgia governor’s office after more than two decades of Republican control.

The historic nature of Bottoms’ victory extends well beyond party politics.

Georgia, once at the center of some of America’s most consequential civil rights battles, has now elected a Black woman to lead its state government. It is a milestone that reflects generations of political participation, organizing and leadership by Black Georgians.

For Atlanta, the moment is especially significant. A former mayor of the city that helped shape the modern civil rights movement will now lead the entire state.

Bottoms’ election opens a new chapter in Georgia’s political history and establishes a milestone that will be remembered far beyond the 2026 election.
