By the early 1900s, Johnson & Johnson’s business was booming. The company expanded its reach, manufacturing consumer products like fumigators (which killed disease-causing insects), dental floss, and disposable diapers in addition to its sterile surgical supplies. As more people learned about the principles of basic hygiene and proper emergency care—sometimes through Johnson & Johnson publications like the 1901 Hand Book of First Aid—they became dedicated consumers of company products. To keep up with demand, the company stretched into new factory spaces to increase production. At the heart of this expansion was the conversion from steam to electric power. The company built its first all-electric Powerhouse in 1907.
