🔎 Episode Overview

In this Flashcards episode of Math! Science! History!, we celebrate the life and legacy of Lillian Baumbach Jacobs, the first female master plumber in the U.S. Just in time for next week's Fix a Leak Week, we explore how Lillian defied societal norms, mastered a trade dominated by men, and became an unexpected icon, even receiving fan mail from soldiers during the Korean War. From her early days learning plumbing alongside her father to becoming the head of Baumbach Plumbers, Lillian's journey was one of perseverance, skill, and leadership. Her legacy not only paved the way for women in the trades but also serves as a powerful reminder that passion and expertise matter more than outdated stereotypes. In this episode, we discuss three major lessons we can take from her story—breaking barriers, following passion over stereotypes, and creating opportunities by challenging norms. Whether you're pursuing a career in STEM, trades, business, or leadership, Lillian's journey proves that no field is off-limits.

🧠 What You'll Learn:

✔️ Break Barriers in Any Industry ✔️ Follow Passion Over Stereotypes ✔️ Create Opportunities by Challenging Norms

It's Black History Month! This week is a repost from season one about Dr. Roger Arliner Young. She was America's first black, female zoologist to get her doctorate. This month I'll be honoring the black, noble goddesses in STEM who inspire, motivate, and forge paths for those who have been marginalized. She is, no doubt, one of my favorite sheroes who succeeded despite our structural racism and antiquated gender bias.
