Ambition, ingenuity, and hard work marked the early growth of Rochester Midland Corporation. It began in 1888, when two men, Daniel N. Calkins and Clarence P. Crowell, purchased the Rochester, New York Agency of the Aromatic Disinfecting Company of Philadelphia, Pennsylvania, a company that supplied equipment and "disinfecting" fluid for restrooms. Under the new company name of Rochester Germicide Company, improvements in the system were made and expansion into manufacturing other products began.

By 1907, Rochester Germicide had opened sales offices in Boston, Toronto, Chicago, Pittsburgh, and Cleveland and was manufacturing and selling hand soaps, floor cleaners, disinfectants, and insecticides.

Over the next several decades Rochester Germicide's product line grew primarily through the needs of and ideas from its customers. The number of branch offices gradually expanded from the original six to include most of the major metropolitan areas throughout the United States.

In the early 1970's, an active acquisition program began and numerous companies and janitor supply businesses throughout the United States were purchased. One of the most significant early purchases was the 1972 acquisition of Midland Laboratories, located in Dubuque, Iowa. Midland Laboratories was an established, well-respected firm in the Midwest United States, and the merger of the two companies gave Rochester Germicide an expanded small package line of chemical products as well as an even greater involvement with insecticides. Later, when Rochester Germicide was to change its company name, the name Midland would be included in the new title, significant of the important role Midland Laboratories had in the company's growth.

To support the rapid expansion, in 1975 the company built a 70,000 square foot facility in Aurora, Illinois, to serve as both the manufacturing and distribution center for the Midwest, Southern and Western United States. Increased efforts in research and development during the 1970's and early 1980's allowed Rochester Germicide to add specialty chemical products for water treatment, industrial maintenance and food processing industries.

"Germicide" no longer identified the great diversification the company had undergone since its inception. In 1989 RMC replaced its existing Toronto manufacturing plant with a new 60,000 square foot production facility in nearby Oakville. The new building houses the headquarters for Rochester Midland Limited, which is responsible for the company's Canadian operations.

In early 1991 Rochester Midland acquired Industrial Chemical Laboratories, a well-known and respected manufacturer of institutional and water treatment products serving sections of the Midwest and Northwest United States. This latest acquisition completed 20 years of extraordinary growth for the company.

Most recently, RMC acquired Protecto, Inc. of Ontario, California in June, 2000. This leading manufacturer of toilet seat covers and other specialty papers will be a valuable addition to the Rochester Midland's Personal Care Division. Today, Rochester Midland's sales force spans the globe with technology far beyond that of the late 1800's, drawing on the expertise and creative chemistry of its seven distinct product divisions. And it's still a family owned business, led by H.D. Calkins (Chairman and CEO), son Bradley (President, Global Division) and daughter Katherine (Senior Vice President, Office of Managing Director) playing an active role in the company's operations.
