Does anyone know anything about John George ALLISON, inventor of the "Allison" Gas Engine? He is a bit of an enigma to me. He traded as JG Allison & Sons Engineers (Estd 1860) at Rectory Works in Sunderland in 1898. His letterhead - which is all I have - also states "Highest Award Prize Medal Newcastle 1887". Does any of this mean anything to anyone? JG Allison died a pauper in 1917 and is buried in an unmarked grave in Mere Knolls Cemetery. He may have had religious scruples, selling out his interest in the Allison Brewery in Sunderland to his two brothers for £5,000 probably in about 1870. The brewery was ultimately taken over by Scottish and Newcastle Brewereies. Clifford Allison.
