Who first used the word whatchamacallit?

1887, Franklin Ulrich. It was the year that the first "Daimler" automobile was released. Due to popular demand, this car sold out around 400 units in its first month. It was a salesman that forgot the name of the Gasket - this lingo was new and fabulous to them. He replaced the concrete noun of "Gasket" with "Whachamacallit". He was fired. Oops.
