Dresser (February 12, 1838 – 1893) was an early leader in the New Thought movement.
Along with his wife Annetta, Dresser was the first proponent of the "Quimby System of Mental Treatment of Diseases", named after Phineas Parkhurst Quimby.
Julius and Annetta were also the parents of prolific New Thought author Horatio Dresser, who, along with them, led a long-time dispute against Christian Science founder Mary Baker Eddy over whether she used Quimby's teaching unattributed in her writing.
