The first recorded chemist in history… was a woman
Her name was Tapputi.
She lived in ancient Babylon nearly 3,000 years ago.
She created perfumes using early chemical processes.
She used distillation, filtration, and extraction.
These are techniques we still use today.
Her methods were recorded on clay tablets.
From ancient perfume labs… to modern chemistry laboratories.
Before modern chemistry… there was Tapputi.
