When 3M introduced Scotch tape in 1930, at the start of the Great Depression, it was a remarkably apt product for a scrimping and saving population — and an extraordinary advance. By combining two recent discoveries, masking tape and DuPont’s impermeable cellophane, 3M scientists had produced a clear, clean, inexpensive binding device, useful for mending rips in a wide spectrum of materials. Musicians used Scotch tape to patch ripped sheet music; women, to fix broken fingernails; accountants, to restore torn ledger books; and banks, to repair ripped currency.
