Celebrating Black Scientists

From the great engineering feats of African Stonehenge and the Egyptian pyramids, to traffic lights, automatic elevator doors, and gas masks, contributions of Black people to society continue to be of astounding significance. At Pacific Science Center, we are excited to celebrate and amplify black voices not just in February, but throughout the year by highlighting the contributions of Black scientists, technologists, engineers, and mathematicians.

We note in 1986 Congress passed Public Law 99-244 (PDF, 142KB) which designated February 1986 as “National Black History Month”. We use the term “Black” to echo this designation of Black History Month, while also recognizing that there is a wide black diaspora (mass dispersion of peoples from Africa during the Transatlantic Slave Trades, from the 1500s to the 1800s) that took millions of people from Western and Central Africa to different regions throughout the Americas and the Caribbean. We therefore recognize and honor the various Afro-Caribbean roots captured within the term “Black” for Black History Month.

Black Scientists

Who inspires you to be your best?

The teens in our Discovery Corps program told us that, while they look up to people who make big discoveries, real inspiration comes from learning how great people overcome obstacles to achieve their dreams.

We worked with the teens to create Path of Persistence, an exhibit honoring some of the Black and African American scientists whose passion, curiosity and determination led to scientific breakthroughs and inventions that enrich our lives.

This is by no means a complete list. Tag us @PacSci on Facebook, Twitter, and/or Instagram to share the names of Black scientists, innovators, and inventors you think should be recognized!.

PacSci Statement on Inclusion, Diversity, Equity, and Access

We believe that curiosity and critical thinking are essential to equity and justice for all. We embrace science as a process of inquiry, discovery, and problem solving that helps us better understand our universe and each other. Science has the power to connect people and to develop solutions for the common good.

We commit to our guests, community, and colleagues that we will:

  • Use curiosity, critical thinking, and innovation to identify, understand, and reduce inequities and barriers to participation in science.
  • Ensure that our facilities, programs, experiences, and the benefits they provide are accessible to people of all backgrounds, and financial, social, physical, and intellectual abilities.
  • Be a community laboratory and living room that is inclusive and welcoming to everyone.
  • Include diverse experiences and perspectives in our work, particularly the voices of people who have previously been excluded.
  • Honor and better reflect the diverse community we serve.
  • Learn from our past, tackle current issues, and create an equitable future.

We prioritize inclusion, diversity, equity and access in order to strengthen our organization and our community. We encourage all members of our community to come together, to celebrate science and each other, and to be curious.

Pacific Science Center is proud to be a member of Washington Employers for Racial Equity, a coalition of Washington businesses that have come together in support of Black Washingtonians, to raise awareness of racial inequity in our state, and to advocate for an equitable future.  

Commitment to Anti-Racism

Pacific Science Center stands with those who are courageously fighting against hate, racism, and injustice. We recognize that not being racist is not sufficient. We must be actively anti-racist, and we commit to doing so. We prioritize inclusion, diversity, equity, and access in everything we do. Curiosity and critical thinking are essential to the dialogue and changes that need to happen. Learn more.

Community and Justice: Urban Conservation and Human-Wildlife Coexistence
