The legal pad was invented by a paper mill worker, 24-year-old Thomas Holley, in Holyoke, Massachusetts around 1888. Holley came up with the idea from his frustration from having to pick up, at the end of the day, the tons of substandard paper scraps that littered the mill floor. He cut the scraps into the same size and stitched them together to make a unified stack of papers, or pads. Since the paper was essentially trash to the mill, they could sell the pads at low prices. Holley’s idea was so successful that he quit his job at the mill and started selling pads full time through the company he created, American Pad and Paper Company, or AMPAD. AMPAD would collect scraps from the local mills and manufacture and sell the pads. In the year 1902, a prominent businessman modified the paper pads by sticking all the halved paper sheets on a sheet of cardboard. Later in 1900, a judge in Holyoke, seeking spaces to write his notes, asked his assistant to find or create a writing pad with a margin on the left side of 1.25”. That request encouraged Holly to add the vertical margin on the left side of the paper to write side notes and indexed revisions. This is what we know today as the legal pad. Holley’s company still exists and they still manufacture notepads in a variety of sizes, shapes, and colors.
Dying the paper yellow would have been a poor business decision for Holley, as it would have increased his prices. It’s for that reason that it’s not believed that he was the one who started the tradition of yellow pads. So how did they become yellow? There is no definitive answer but many theories. One is that research in color psychology can back up the claim that yellow stimulates the mind. Therefore yellow was chosen for those in the legal profession because it stimulated their creativity and mental capabilities. A second theory is that yellow provides a background that contrasts well with black ink without glare, making text easier to read and providing a professional feel. And a third theory is that Holley or his successors eventually decided to dye the paper to hide the fact that the pads were made from scraps of varying ages and quality, and yellow was the cheapest or most readily available dye at the time.
