Due to the creative genius of members of the Ingraham family, many of the Ingraham clock designs were not to be duplicated by other American companies. Elias Ingraham, who lived from 1805 until 1885, was a noted clock case maker who received 17 U.S. patents for designs and manufacturing processes for clock cases. The graceful figure 8 designs on Ingraham clock doors is one fine example of his engineering skill and eye for appealing looks for clocks.

The Ingraham name in clocks continues to survive. The Ingraham Company was sold to McGraw-Edison in 1967. Electric clocks continue to be made using the Ingraham trademark.
