Murray joins John McEnroe , Boris Becker, Andy Roddick and Lleyton Hewitt as the only four-time winners of the Wimbledon warm-up event in the Open era.
It is Murray's third ATP title of 2015 after his victories on clay in Madrid and Munich, earning him a cheque for 381,760 euros ($433,507) and continuing his superb form since his April wedding.
With 34 career ATP titles, including six on grass, Murray moves up to 18th on the Open era list -- level with Arthur Ashe, Michael Chang and John Newcombe.
Even more significantly, it is the world number three's first title on grass since his historic Wimbledon triumph in 2013.
That career-defining success two years ago came after his third victorious campaign at Queen's and, with Wimbledon just eight days away, Murray's ruthless 64-minute rout of the world number 17 shows he is in the mood to mount a sustained challenge for a second All England Club crown.
"I played better as the week went on. I came up with some great shots today and I had to play that way if I wanted to win," Murray said.
"You want to go into Wimbledon with grass matches under your belt. I'm playing better than I did in 2013 but it's extremely difficult to win these events."
