The Grimwade Family, hailing from Australia, began their journey in the business world in the late 19th century. The family’s patriarch, Frederick Grimwade, an English immigrant, established the company that would eventually become the iconic Reckitt Benckiser. He started with a small pharmaceutical business, focusing on the production of simple household items like soap and starch.

As the company grew, so did the Grimwade family’s influence.
