The L. Perrigo Company was founded in 1887 in Allegan, Michigan, by Luther and Charles Perrigo. The Perrigo brothers had moved to Allegan County, Michigan, a few years earlier from New York. Once in Michigan the brothers established a modest business. Luther Perrigo ran a country general store and apple drying business, while Charles helped with sales. Luther decided to package generic home remedies and sell them to other small country stores like his own. The first packaging plant for these medicines was run out of Charles Perrigo's home, but Charles soon moved to Ohio, leaving the business entirely to his brother. Luther became president of the firm when it incorporated in 1892. Perrigo remained a family-owned business for 90 years. Five of the company's seven presidents were descendants of Luther Perrigo, who died in 1902. His son Harry became president at that time, holding the position for the next 49 years.
