Jackson or Morton?

Both Morton and Jackson laid claim to the discovery of ether anesthesia, the latter receiving initial strong support in Europe, while Morton had the backing of Massachusetts General Hospital.  Years of legal wrangling ensued, without any clear resolution. 

Charles Thomas Jackson eventually suffered a mental breakdown, or possibly a stroke, and was admitted to the McLean Asylum in 1873.  He died there on August 28, 1880.

While generally remembered for his prominent role in the introduction of ether anesthesia, William Thomas Green Morton was never able to derive financial benefit from the discovery nor could he enforce his patent.  He abandoned dentistry for farming and became impoverished from years of ether-related litigation.  Morton died of apoplexy on July 15, 1868.
