The Household & Commercial Products Association (HCPA) was saddened to learn about the passing of Montfort “Monty” Johnsen on September 4, 2021. Johnsen was an aerosol industry expert, inventing five aerosol-related patents, authoring 10 aerosol books, including The Aerosol Handbook (Editions 1 & 2), which is better known as The Bible of the aerosol industry, and serving on the HCPA Board of Directors for a record 11 years.

“Monty was a dedicated member of HCPA since 1953. He was elected Chair of the Aerosol Products Division in 1974 and served as Chair of the Board of Directors in 1981,” said Steve Caldeira, President & CEO, HCPA. “Monty’s contributions to HCPA and the aerosol industry were unmatched. I know he was very proud of attending all 127 meetings that HCPA hosted during his time as a member. He and his wife, Marie, were fixtures at these events, and they looked forward to interacting with colleagues and discussing industry issues.”

Johnsen joined the aerosol industry in 1953 with the Continental Filling Corp. From there, he became a founding member of Peterson Filling & Packaging Co., now known as KIK Custom Products. Johnson served as the Technical Editor for Spray from 1985 until his retirement and authored more than 300 columns for the magazine. He also traveled the world as an aerosol technology expert and was regarded as an expert witness to provide insight and information in legal matters with regard to aerosol technology.

“HCPA’s Aerosol Products Division benefitted significantly from Monty’s knowledge, and we were proud to present him with the Charles E. Allderdice Award – HCPA’s most prestigious honor – in 2003 for his many achievements of the aerosol industry,” said Caldeira. “Monty gave more than 60 years of service to the aerosol products industry and his legacy will live on through the innovations and advancements we continue to make every day in his honor.”
