In the space of a few decades, Van Dyne and Crotty were able to grow their initial $500 investment into a $2–3 million business. Van Dyne-Crotty is also credited as being the first company east of the Mississippi River to rent an entrance mat, also known as a "walk off mat." Lloyd Van Dyne died on April 28, 1962, and Fergus Crotty followed just months later. The company was passed on to Fergus' three sons: Robert, Frank and L. William Crotty.
