The 26-year-old defeated world number one Novak Djokovic 6-4 7-5 6-4 amid jubilant scenes on Centre Court to emulate 1936 winner Fred Perry.
Twelve months ago Murray lost in the final to Roger Federer but has had an incredible year that has brought him Olympic gold, a first grand slam trophy at the US Open and now Wimbledon glory.
The nearly 15,000-strong crowd roared Murray on, with thousands more watching on the big screen at the All England Club also making their voices heard.
Millions more were glued to their TV sets, and nowhere was the support for Murray more heartfelt than in his home town of Dunblane.
In a BBC documentary on the eve of Wimbledon, Murray spoke movingly about how much it meant to him to make the town proud after the tragedy of the school shooting in 1996 that left 16 children and one teacher dead.
Asked what he wanted to say to the people of Dunblane, Murray said: "I'd just say thanks for always supporting me. I'm glad I managed to win this one for them.
"I spoke to my grandparents on the phone. They were watching the match at the local sports club where I grew up playing. It was absolutely packed in there."
In now traditional fashion, Murray climbed up to his box to celebrate with his family, friends and support team, and he headed straight for Lendl.
One of the biggest disappointments of Lendl's own career was that he did not win Wimbledon, losing twice in the final.
Murray said: "Obviously ideally he would have won it himself, but I think this was the next best thing for him. I'm saying it seriously.
"He believed in me when a lot of people didn't. He stuck by me through some tough losses the last couple of years. He's been very patient with me. I'm just happy I managed to do it for him."
Murray praised Lendl, who he began working with 18 months ago, for helping him make the step up from a player who did not win a set in his first three grand slam finals to now a multiple slam champion.
"He's made me learn more from the losses that I've had than maybe I did in the past," said Murray.
"I think he's always been very honest with me. He's always told me exactly what he thought. And in tennis, it's not always that easy to do in a player/coach relationship.
"Last year after the final he told me he was proud of the way I played because I went for it when I had chances. It was the first time I played a match in a grand slam final like that.
"He's got my mentality slightly different going into those sort of matches."
The support for Murray has been noticeably greater this year and it reached a peak during Sunday's match.
The Scot has been greeted like a rock star wherever he has gone this fortnight, but he has no desire to live a rock star lifestyle.
"I don't know how it will change my life," he said. "I hope not too much."
Murray hailed the contribution of the crowd, saying: "It really helps when the crowd's like that. Especially in a match as tough as that one where it's extremely hot, brutal, long rallies, tough games, they help you get through it.
"It was the best atmosphere I've played in here."
Murray has grown used to dealing with the pressure of being the home hope at Wimbledon but conceded that does not make it easy.
As soon as Rafael Nadal and Roger Federer went out, it was assumed he would get to the final, and he hopes when he returns as defending champion next year the weight on his shoulders will have lifted.
"It's really hard," he said. "For the last four or five years, it's been very, very tough, very stressful, a lot of pressure. The few days before the tournament are really difficult as well.
"The last two days haven't been easy. It's so hard to avoid everything because of how big this event is, but also because of the history and no Brit having won. It's been very, very difficult.
"I think I felt a little bit better this year than I did last year. I think now it will become easier. I hope it will."
Murray has not always had an easy relationship with the media, but at the moment of victory he turned to the press seats and raised his fists in triumph.
"I was staring in the direction of quite a few of the guys in the press," he said.
"Obviously I've had a difficult relationship at times over the years. The last few years have been much better. I know for you guys it's important that I win this tournament. I worked as hard as I could to do it."
