Rose Knox

In 1914 after six years of secretly running the company, Rose Knox revealed that she'd assumed her deceased husband's position as the company's president. With creativity and persistence, she then skillfully drew upon traditional ideals of domesticity and womanhood to turn Knox Gelatine into an iconic American brand and herself into a business celebrity.

“Rose Knox: How One Woman Mixed Kitchen and Boardroom to Remold an American Business is a well-written and meticulously researched book that reveals the fascinating story of an amazing woman. Over her long life, Rose Knox was a trailblazer and a remarkably accomplished woman. Born in 1857 and living until 1950, she "did it all", maintaining her image as a devoted wife and mother and also a business leader in a world dominated by men. Charles Knox established Charles B. Knox in 1891, producing Knox gelatine, a product that could be used in a wide variety of recipes for the "modern" homemaker of the time. His wife Rose always played a behind-the-scenes part in the business, but her public role was that of a supportive wife and mother to their two sons. She developed recipes and a cookbook and exemplified how the product could assist the homemaker with her culinary duties. After Charles death in 1908, she inherited the business and slowly emerged as the full leader of this successful enterprise. We see her navigate the business's growth and struggles, the changing landscape of advertising and manufacturing, and the obstacles a woman faced as the head of a large company. The story of a singular woman who connected with other women as a mother and homemaker, yet also claimed her place in the business world over a long and interesting historical period makes this book a fascinating look at an individual yet also a look at the world she lived in. (echoes of Martha Stewart long before Martha Stewart). Greenfield has done meticulous and documented research that illuminates the story, and includes photographs, documents, ads, handwritten notes, and numerous recipes that add further detail and interest to this book.”

“We often say there aren't enough women role models in business. But there are. There were. Rose Knox built a national company, raised a family, and inspired millions — and then history forgot her. This book is a reclamation. A reminder that we don't have to start over. We just have to remember.”
