The youngest child of George Adams senior (1709-1772) by his second marriage, Dudley Adams was apprenticed to his brother George to train as a mathematical instrument maker.

In 1794, possibly as a result of supplying 28 inch globes for Lord Macartney's mission to China, he was appointed globemaker to George III, a prestigious post previously held by his father. However, he lived well beyond his means, and his bankruptcy in 1817 ended the Adams instrument business, founded in 1734.
