Show Notes
When Lisa Clark was diagnosed with type 1 diabetes at just five years old, her life—and her family's—changed forever. Managing the condition in the 1970s meant urine testing, stainless steel syringes, and a revolving door of hospital visits. But what followed is one of Australia’s most remarkable medical stories.
Her father, Stanley Clark, an electronics engineer with zero medical background, took matters into his own hands. Driven by love for his daughter, Stan retreated to his home workshop and emerged with the world’s first portable blood glucose tester—a device that would not only transform Lisa’s life, but help millions globally.
In this episode, Lisa shares the story behind the invention that reshaped diabetes care, the beautiful chaos of building a global breakthrough from a backyard shed, and how a humble Aussie dad left a legacy the world should never forget.
Here’s what we cover:
-What life with type 1 diabetes looked like in the 1970s (urine tests and boiled needles!)
-The moment Lisa’s dad decided to “fix” diabetes monitoring himself
-How he built the world’s first home blood glucose meter in a week—from scratch
-The family-run factory that couldn’t keep up with global demand
-Why Stan turned down a millionaire’s deal—and a Rolls Royce
-The heartbreaking phone call that warned: “You’ll be out of business in six months”
-How Lisa has managed her diabetes for over 50 years without burnout
-Her handwritten letter to diabetes—and the legacy she’s determined to protect
… and so much more.
