Jackson’s life was marred by various priority disputes. When Samuel Morse patented his electric telegraph in 1840, Jackson claimed that he had given Morse the fundamental ideas while on the return voyage from Europe in 1832. However, he had never developed those speculations beyond a preliminary working model. More bitter was his dispute with the dentist William Morton concerning the use of ether in anesthesia.

Although Morton first learned of the anesthetic properties of ether from Jackson, it was Morton’s own further research that led to successful painless surgery in 1846. Morton applied for a joint patent with Jackson, but Jackson always insisted that the discovery was his own and even continued the fight after Morton’s death in 1860. Jackson was beset with mental illness during his last years and died in the McLean Asylum in Somer-ville, near Boston, on Aug. 28, 1880.
