The Breakfast Club: IDKMYDE – "Your Phone Knows Who's Calling Because of Her"

Date: February 13, 2026
Host: B Dot (on behalf of The Breakfast Club – DJ Envy, Jess Hilarious, Charlamagne Tha God)
Theme:
A deep dive into the unrecognized impact of Dr. Shirley Ann Jackson, a pioneering Black physicist whose research made everyday communication technology like caller ID, call waiting, and fiber optics possible.

Episode Overview

In this episode of the "I Didn't Know. Maybe You Didn’t Either" series (IDKMYDE), the host spotlights Dr. Shirley Ann Jackson and her transformative contributions to modern telecommunications. The show both educates and challenges listeners to reconsider who we credit for the tools and technologies we use daily, especially during Black History Month.

Key Discussion Points & Insights

1. The Overlooked Legacy (00:08–02:05)

Introduction of Dr. Shirley Ann Jackson:
B Dot reveals three "useless facts" that are, in fact, crucial historical context:
- Caller ID, call waiting, and fiber optics were developed from the research of Dr. Shirley Ann Jackson, an unsung Black woman in STEM.
- "Her name was Dr. Shirley Ann Jackson, and she earned her PhD in theoretical physics in 1973. She's the first black woman to do so at MIT." (B Dot, 00:33)
- Before such advances, all phone calls were manually connected by human operators, often strangers listening in.
Audience Engagement:
B Dot asks if anyone in the audience actually knew about Dr. Jackson, highlighting how hidden her story is:
- "Were you familiar with Dr. Shirley Ann Jackson? Cause I wasn't." (B Dot, 01:49)

2. How Dr. Shirley Ann Jackson Changed Communication (02:18–04:28)

Concrete Impact on Daily Life:
- The host humorously points out how we rely on caller ID and customizable ringtones, yet rarely consider whose contributions made this possible:
  - "You got that boy number saved and your phone is Brokey. And that will pop up on the screen every time he called Brokey. But you ain't never thought about who made that possible, have you?" (B Dot, 02:18)
Technical Contributions:
- Dr. Jackson's research in semiconductors and fiber optics powered the creation of caller ID, call waiting, and the communications systems underpinning today’s phone and internet technologies.
- "Her work laid the groundwork for all of that. And yet how many tech histories give her front page credit? Very few. Again, hidden in plain sight." (B Dot, 03:07)
Wider Recognition and Lifetime Achievements:
- Dr. Jackson’s influence continued:
  - She chaired the Nuclear Regulatory Commission.
  - She became the president of Rensselaer Polytechnic Institute.
  - She received the National Medal of Science.
- "A lifetime of excellence built on foundational breakthroughs." (B Dot, 03:55)

3. The Importance of Remembering Black Excellence (throughout)

Historical Context:
- The episode ties Dr. Jackson’s legacy to Black History Month and Carter G. Woodson’s mission to spotlight Black achievement:
  - "Your connections ain't just Digital. They're historical. 100 years after Carter G. Woodson carved a space to Honor Black achievement, Dr. Shirley Ann Jackson's research powers the way the world communicates." (B Dot, 04:19)
Challenging the Listener:
- The show challenges the audience to recognize the invisible architects of systems we use and not let their stories slip into obscurity:
  - "Systems get built. They get used. Then most people forget who made them work." (B Dot, 03:33)
  - "And I didn't know. Maybe you didn't either." (B Dot, 04:27)

Memorable Quotes & Moments

On the irony of ignorance:
"Her work on semiconductors and fiber optic technology and other stuff that I have no clue what the hell I'm talking about helped create caller ID, call waiting, the fiber optic communication system we use." (B Dot, 02:34)
On the legacy of Black inventors:
"Again, hidden in plain sight. Just like the marching 100. Just like Alfred Crowley. Just like Marie Van Britten Brown." (B Dot, 03:07)
Final call to action:
"So this Valentine's Day, you think about who's calling, baby. But also remember the black woman whose science makes that notification possible." (B Dot, 03:59)

Welcome back, know it alls to another episode of the most anticipated podcast on the Black Effects podcast network, especially in February, entitled I didn't know. Maybe you didn't either. And I'm your host, B Dot. And please make sure you're following us on Instagram idkmyde with an underscore before it and at the end. And make sure you're subscribed on YouTube to check out visual content. Just put IDKMYDE in your search bar and you know you can do all of that right there from the privacy and the comfort of your own phone. And to kick off today's episode, I'd like to give you three of the most useless facts you'll never need, not a day in life. Up first, caller id, call waiting and fiber optics, all technology we take for granted, were all built on research by a black woman. Your second useless fact, her name was Dr. Shirley Ann Jackson, and she earned her PhD in theoretical physics in 1973. She's the first black woman to do so at MIT. And your third useless fact? The very first commercial telephone service began in 1877. And for decades after, most calls was connected manually by a human operator. Those have been your three useless facts. Caller id, call waiting and fiber optics were all technology built on research by a black woman. Your second useless fact. Her name was Dr. Shirley Ann Jackson, and she was the first black woman to earn a PhD at MIT in 73. And your third useless fact? The very first commercial telephone service began in 1877, and your calls were connected manually. I mean, a stranger was sitting there listening while they was connecting your calls. But for today's episode, were you familiar with Dr. Shirley Ann Jackson? Cause I wasn't.

C (2:05)

I didn't know. Maybe you didn't know. I didn't know. Maybe you didn't know. I didn't know. Maybe you didn't need. I didn't know. I didn't know. I didn't know.

B (2:18)

You got that boy number saved and your phone is Brokey. And that will pop up on the screen every time he called Brokey. But you ain't never thought about who made that possible, have you? Dr. Shirley Ann Jackson, a theoretical physicist, she broke barriers in the 70s that we still use today. Her work on semiconductors and fiber optic technology and other stuff that I have no clue what the hell I'm talking about. Help create caller ID call waiting, the fiber optic communication system we use. Basically, the fact that you know that that's brokey calling. And you can connect the phone instantly or decline exists because of the research of Dr. Shirley Ann Jackson. Seriously, think about that for a second. Every zoom call that you don't want to be on for work, every text that you leave on red, every FaceTime you ignore. Remember when every person in your phone had a different ringtone? Her work laid the groundwork for all of that. And yet how many tech histories give her front page credit? Very few. Again, hidden in plain sight. Just like the marching 100. Just like Alfred Crowley. Just like Marie Van Britten Brown. If you've missed the previous four episodes, you have no clue what that means. But systems get built. They get used. Then most people forget who made them work. Dr. Jackson didn't invent these technologies to be famous. She solved critical problems. Then the world caught up. And she didn't stop there. Dr. Jackson went on to chair the Nuclear Regulatory Commission. She became the president of the Rensselaer Polytechnic Institute, and she received the National Medal of Science. A lifetime of excellence built on foundational breakthroughs. So this Valentine's Day, you think about who's calling, baby. But also remember the black woman whose science makes that notification possible. Your connections ain't just Digital. They're historical. 100 years after Carter G. Woodson carved a space to Honor Black achievement, Dr. Shirley Ann Jackson's research powers the way the world communicates excellence that history often overlooks. And I didn't know. Maybe you didn't either.
