Scotch Tape
Richard Drew, the inventor of Scotch tape, cut his teeth as an inventor by creating masking tape in his spare time. In his first job as a lab tech at 3M (known then as Minnesota Mining and Manufacturing), he
delivered sandpaper samples to auto manufacturers, and after hearing many an auto painter curse over their DIY masking solutions, he decided to design the perfect tape. He worked on it at 3M at first, but after he was scolded and told to get back to work, he continued the project at home. Drew eventually made his masking tape from crepe paper, cabinetmaker’s glue, and glycerin in 1925, and got a big
promotion.
Another industrial problem came to his attention soon after: Bakeries had started using newly invented cellophane for packaging, but had nothing attractive to seal it with. So Drew started experimenting with a clear tape. The adhesives he used on the masking tape looked brown, so he had to invent a new type of adhesive to make sure the tape stayed clear. The result was a cellophane tape with adhesive made from oil, resins, and rubber. As the story goes, the name “Scotch tape” was inspired by an early version of Drew’s masking tape, which had adhesive only on the edges, causing one auto painter to ask why Drew was so “Scotch” — a slang term for “cheap” at the expense of Scottish people. Scotch tape
debuted in 1930, right at the start of the Great Depression, and as more and more households had to be thrifty and resourceful to survive, the product came along right in the nick of time. People used Scotch tape for everything from mending clothing to capping milk bottles — and even
repairing cracked eggs.
