Masking Tape and Clear Adhesive Tape
Richard G. Drew (1899-1980)
Drew's first tape invention was a masking tape made for painters in 1923. This early masking tape was a wide paper tape with adhesive on only the edges of the tape - not in the middle. Drew made an improved tape called Scotch (TM) Brand Cellulose Tape in 1930. This tape was a clear, all-purpose adhesive tape that was soon adopted worldwide. The first tape dispenser with a built-in cutting edge was invented in 1932 by John A. Borden, another 3M employee.
