G. Gordon Liddy, a cloak-and-dagger lawyer who masterminded dirty tricks for the White House and concocted the bungled burglary that led to the Watergate scandal and the resignation of President Richard M. Nixon in 1974, died on Tuesday in Mount Vernon, Va. He was 90.
His death, at the home of his daughter Alexandra Liddy Bourne, was confirmed by his son Thomas P. Liddy, who said that his father had Parkinson’s disease and had been in declining health.
Decades after Watergate entered the lexicon, Mr. Liddy was still an enigma in the cast of characters who fell from grace with the 37th president — to some a patriot who went silently to prison refusing to betray his comrades, to others a zealot who cashed in on bogus celebrity to become an author and syndicated talk show host.
