The story of Percy Harms Corporation begins with a simple problem faced by molders and mold makers: plastic parts sticking to steel molds. This challenge sparked the creation of a small but innovative company that would grow from a family garage into a recognized name in the aerosol industry. The journey of Percy Harms Corporation is a tale of persistence, family collaboration, and practical ingenuity.
Early Beginnings in a Family Garage Aerosol industry leader
In 1953, Percy Harms was already selling tool steel to molders and mold makers. His customers asked for a mold lubricant to prevent plastic parts from sticking to steel molds. Percy teamed up with his cousin, Howard Klemm, to develop four aerosol products: a silicone-based mold release, a rust preventive, a tapping fluid, and a blue layout dye. These products formed the company’s first minimal product line.
The business was incorporated as Perc. E. Harms Corporation. Percy chose this name to avoid the nickname “Perky Harms” that might come from using his full name. The company operated out of a garage at the family home on George Street in Skokie, Illinois. This humble start laid the foundation for what would become a growing enterprise.
Moving Beyond the Garage
By 1959, Percy decided to rename the company Percy Harms Corporation, embracing his full name. Despite the name change, the company still did not manufacture its own products. Instead, it stored inventory in the family garage, which became a point of tension at home. Percy’s wife, Edna, insisted on finding a proper warehouse space to keep the business separate from their living area.
Responding to Edna’s insistence, Percy rented a small warehouse to store products. This move marked the company’s first step toward a more professional operation and allowed the family to separate business from home life. It also set the stage for future growth.
Family Expansion and Product Development
In 1963, Percy’s two sons, Jim and Henry, joined the company to help expand sales efforts. Their involvement brought fresh energy and focus to the business. Around the same time, Jan van der Graff, a chemical engineer, joined as an outside partner. Jan’s expertise in product development was crucial for the company’s evolution from a reseller to a manufacturer.
Jan’s role allowed Percy Harms Corporation to begin developing its own products, moving beyond simply selling items made by others. This shift was essential for the company’s long-term success and helped build a stronger brand identity.
Growth and Moving to a Larger Facility
By 1976, the company had outgrown its small warehouse and needed a larger space. Percy Harms Corporation moved to a former pudding factory in Wheeling, Illinois. This new location allowed the company to install its own aerosol filling equipment, a major step toward manufacturing independence.
The production line was far from new or high-tech. The storage tanks were secondhand, the can labeler was converted from an old baby food jar labeler, and the filling equipment was all used. Despite these humble beginnings, the company spent 18 months installing and fine-tuning the equipment.
Henry Harms took charge of setting up the aerosol filling line, while Percy and Jim continued focusing on sales. This division of labor helped the company balance production and market growth effectively.
