Their story demonstrates that invention does not have to begin in a lab; it can start at the kitchen table. Lily’s involvement at a young age makes their journey especially inspiring for students and families alike. 
A Legacy of Ingenuity and Family
From global enterprises to practical household inventions, these families remind us that innovation can start anywhere. Rich and Liz Muller, the Toyoda family, the Wales duo, the Gores, and the Hooks all prove that invention is not just a personal journey. It is a shared one.
