The former Tetlow Manufacturing Company factory in Philadelphia's Chinatown is a testament to the city's rich history in the cosmetics industry. This five-story brick building, located at 10th and Cherry streets, has witnessed the rise and fall of a business that played a pivotal role in shaping American beauty standards. The story of Henry Tetlow, an English immigrant, and his innovative face powders is a fascinating journey through industrial chemistry, Victorian beauty culture, and family dynamics. Tetlow's discovery of zinc oxide as a safe and affordable alternative to toxic face powders revolutionized the industry, making cosmetics accessible to the working and middle classes. This development coincided with the growth of Chinatown and the increasing immigration from Europe, creating a vibrant and diverse neighborhood. The factory's location in Chinatown reflects the area's transformation into a hub of light manufacturing and a melting pot of cultures. However, the Tetlow story also highlights the challenges of family-run businesses. A feud between Tetlow and his brother led to a split in the company, diluting its brand identity and profits. The subsequent court battle over Tetlow's will further exacerbated the situation, leading to the company's eventual decline and relocation in the 1930s. The Philadelphia Historical Commission's consideration of adding the factory to the historic register is a recognition of its historical significance. It represents a turning point in the cosmetics industry, where innovation and accessibility went hand in hand. As the city continues to preserve its past, the Tetlow factory stands as a reminder of the impact of individual entrepreneurs on the development of American culture and industry. This story is a testament to the power of innovation and the challenges of family dynamics in the business world, all set against the backdrop of a rapidly changing Philadelphia.
