Black History Month asks us to look beyond the highlight reel of tech history and recognize the people whose work actually built the systems the world runs on. These innovators were not always household names, but their fingerprints are on the technologies we use every day: the devices in our hands, the satellites orbiting above us, the code that interprets our data, and the infrastructure that keeps digital life functioning. Their contributions are not side notes in history. They are the story.
This list continues our effort to lift up the builders whose brilliance shaped modern technology and whose brilliance we all aspire to. If you’re looking to learn about even Black innovators in tech, you can check out last years list here.
James E. West
James E. West helped solve a problem that seems simple now: capturing sound clearly, reliably, and cheaply. In 1962 at Bell Labs, he co-invented the electret microphone, a design that became the foundation for nearly every microphone in use today. That includes the ones in smartphones, laptops, hearing aids, and the meeting rooms we rely on every day. His innovation made audio technology scalable at a time when affordability and consistency were real barriers.
West spent his career pushing for diversity in engineering, reminding the industry that who gets to build technology shapes the future of the field. His work lives inside the hardware, and his advocacy lives inside the pipeline.
Dr. Gladys West
If you have ever followed a GPS map, you have interacted with the work of Dr. Gladys West. She developed the mathematical models that allowed satellites to calculate precise positions on Earth, correcting for the planet’s uneven shape and constant movement. Before her work, the idea of accurate, everyday navigation simply was not possible. Her research helped transform GPS from a military tool into a global resource used by emergency responders, airlines, shipping companies, and anyone trying to find the nearest grocery store.
Dr. West worked for years behind the scenes, often without recognition, because much of her research was classified. Today, her legacy is clear: she made accuracy accessible to the world.
Dr. Joy Buolamwini
When Dr. Joy Buolamwini noticed that facial recognition programs struggled to detect her face, she decided to test the systems more deeply. What she found was both obvious and alarming: the algorithms performed significantly worse on darker skin tones and on women. Her research forced companies to confront how bias enters technical systems, through the absence of diverse data and oversight. Dr. Buolamwini’s work has reshaped global conversations about responsible AI and sparked policy changes in government and industry.
She helped move the conversation from “AI might be biased” to “we have measurable proof, and we must address it.” Her leadership shows how research can shift an entire field.
Dr. Aprille Ericsson
Dr. Aprille Ericsson broke barriers early in her career, becoming the first African American woman to earn a PhD in Mechanical Engineering from Howard University, as well as the first African-American woman to receive a Ph.D. in engineering at the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC). At NASA, she has worked across major missions, contributing to guidance, navigation, and control systems that help satellites collect climate data and support scientific research. Her expertise has influenced projects ranging from Earth observation to spacecraft design, and her work supports technologies used by governments, researchers, and communities worldwide. What makes Dr. Ericsson’s story especially powerful is her commitment to opening doors for young people. She has spent years advocating for STEM pathways, mentoring students, and emphasizing that access is directly tied to innovation.
Otis Boykin
Otis Boykin improved the reliability of electronic devices by inventing a precision resistor that became essential across multiple industries. His design made radios, televisions, and computers more dependable and affordable, which accelerated their adoption during a critical period of technological growth. One of Boykin’s most meaningful contributions was his work on early pacemaker technology, where his resistor helped make life-saving devices safer for patients.
He held multiple patents and continued developing new electronic components throughout his career. Boykin’s impact sits inside the everyday tools we take for granted, reminding us that foundational components often drive the biggest change.
Tope Awotona
Tope Awotona created Calendly out of a frustration many people shared but simply adapted to. Instead of accepting endless scheduling emails, he built a tool that eliminated the friction altogether. What started as a straightforward idea became a platform used by millions of people, from freelancers to enterprise teams. As remote work expanded, Calendly became infrastructure for how organizations coordinate time and manage relationships.
Awotona’s story shows how clarity, persistence, and personal investment can turn a simple problem into a category-defining solution. He built something that feels obvious now, but only because he created it first.
Kimberly Bryant
Kimberly Bryant founded Black Girls Code after noticing a gap that many people had learned to overlook: young girls of color were rarely encouraged to see themselves as future technologists. She created a space where they could learn programming, build projects, and experience what it feels like to be centered in the learning environment. The organization has grown nationally, inspiring thousands of young people to explore technology with confidence and curiosity. Bryant reframed the pipeline conversation by focusing on early exposure for girls. Her work demonstrates how representation and opportunity for youth will change the trajectory of entire communities.
Lonnie Johnson
Lonnie Johnson is often recognized for inventing the Super Soaker, but that is just one chapter in a long engineering career. Before the toy became a cultural phenomenon, he worked at NASA on projects that contributed to the Galileo and Cassini missions. His background in thermodynamics and energy research has led him to pursue innovations in renewable power and advanced battery technology. Johnson’s career spans aerospace engineering, consumer products, and energy solutions, showing a rare combination of imagination, creativity, and technical depth.
He is a reminder that innovation does not follow a single path, and that creativity can span multiple industries over a lifetime.
Dr. Ayanna Howard
Dr. Ayanna Howard is a leading researcher in robotics, artificial intelligence, and assistive technologies. Her work explores how intelligent systems can support children with disabilities, respond to hazards, and interact more naturally with people. She has published widely, led major research initiatives, and shaped engineering education through her leadership roles. Dr. Howard’s ability to blend advanced research with community impact sets her apart in a rapidly evolving field.
Her work continues to influence how we design robots and AI systems that serve real human needs. She shows that innovation is most valuable when it deepens our humanity.
Marie Van Brittan Brown
Marie Van Brittan Brown invented the first home video security system in 1966, driven by her desire to improve safety in her own neighborhood in Queens. She designed a system with a camera, a sliding panel viewer, two-way audio, and a remote-controlled lock, features that were decades ahead of their time. Brown also built an emergency alert mechanism that could notify police directly, creating one of the earliest examples of integrated home security.
Her invention became the foundation for modern security technology, influencing everything from apartment intercoms to smart doorbells. Brown’s work shows how community needs often spark the most impactful innovation. She is a reminder that protecting and strengthening neighborhoods can change entire industries.
Why This Matters at i.c.stars
Black History Month gives us space to celebrate and honor the innovators whose work built the world we live in, and to recognize how many of those stories have gone unacknowledged for far too long. The technologists in this list changed what was possible in their fields, often while navigating barriers that had nothing to do with talent and everything to do with opportunity and access.
At i.c.stars, we see the next generation of leaders carrying that same spark. Our participants learn to lead with purpose, solve complex problems, and design systems that strengthen their communities.
Expanding opportunity isn’t just symbolic work; it’s foundational and structural work. It determines who gets to design the systems our cities, industries, and communities will rely on next. Opportunity and access determine who gets to continue building on top of the foundation that these tech innovators (and many more) created.
We believe that tech should be accessible for everyone and that starts with creating pathways for innovation, leadership, and opportunity. This Black History Month, let’s not only celebrate these innovators who shaped our world but also invest in the future of Black excellence in tech.
