Definitions of dunderhead on the Web:

dunce: these words are used to express a low opinion of someone's intelligence

The Dictionary of Americanisms offers: "DUNDERHEAD. Blockhead; dolt. The same as the English provincialisms dunder-knoll and dummer-head."

The American Heritage concurs in the possibility of the term deriving from doner, thunder, in Middle Dutch.
