A flinty, austere, exacting figure, Tyrie has been chair of both the Treasury select committee since 2010, but probably reached the zenith of his influence leading the Parliamentary Commission on Banking Standards, which helped shape the post financial crisis framework for the banking system, pushing the government rather further than it wanted to go, in the process.
Set up in 2012, in the wake of the LIBOR interest-rate-fixing scandal, the Commission yomped through a prodigious amount of policy work at a gruelling pace.
Its vast reports had huge leverage over the post-crisis banking legislation, not least because the authors sat in both the Lords and Commons - and those in the Lords, including the former Chancellor Lord Lawson, and the Archbishop of Canterbury, Justin Welby, were influential voices in debates on banking legislation, at a time when those issues were politically radioactive
By the end of its life, relations on the Commission had frayed to the point that members were briefing against each other in pretty venomous terms.
Despite that, the exercise was so influential that it may be a long time before another government creates such an effective whip for its own back - and ministers certainly did not fancy setting up a second Parliamentary Commission, this time to review the future of the Civil Service, and the proposal was eventually fought to a standstill.
It is no coincidence that Tyrie's statement announcing his departure noted that "stronger committees now demand better explanations for the decisions made by ministers, regulators, and quangos than hitherto."
And as chair of the super-committee of select committee chairs, the Commons Liaison Committee, he worked hard to underpin the new status and powers of the select committee system.
He also tried to bring in a more exacting interrogation of the prime minister in the Liaison Committee's termly hearings with the PM, once provoking an exasperated David Cameron to shoot back at him: "You don't know what you're talking about" - as he probed the UK's involvement in the Syrian civil war.
In a similar vein, Tyrie also led the all party parliamentary group on Rendition, which pursued evidence of UK complicity in the Bush administration's seizure of terrorist suspects.
Never a minister, and only briefly a shadow minister, Tyrie arguably made his biggest mark on political history as a special advisor to Chancellor Norman Lamont - he had been drafted in on a temporary basis to help out at the Treasury, in the early months of John Major's premiership, and one of his final task was to recommend a successor.
And his choice, on the basis that what was needed was less a policy advisor and more a spin doctor, was a bright young chap named David Cameron.
The rest is history.
If there is any one MP who has dramatised the increased clout of the Commons select committee system, it is Andrew Tyrie - who announced today he is quitting Parliament at the election.

Six Ruairi Convery points helped Derry lead 1-8 to 0-6 at half-time with Gareth O'Kane netting on 16 minutes.
However, the Saffrons were ahead within 13 minutes of the restart after a goal from league debutant Donal Nugent.
Antrim moved seven ahead at one stage and Convery's injury-time goal was mere consolation for the Oak Leafers.
The game saw the Saffrons in Division Two action for the first time since 2003 after their annus horribilis last year when they suffered championship and league relegation.
A losing start looked in prospect for the Saffrons, under new manager PJ O'Mullan, as Derry led by five at the break.
Two long-range Convery frees gave Derry an early lead as Liam Watson, back to league duty after a four-year absence, was off target from a couple of placed balls.
Points from Ciaran Clarke and James Black did bring the Saffrons level but O'Kane's 13th-mninute goal helped Derry move into a 1-4 to 0-3 lead.
With Shane Farren contributing a couple of fine points, Derry moved five ahead by the interval but the game turned swiftly in Antrim's favour in the 13 minutes after half-time as the Saffrons hit an unanswered 1-4.
Nugent flicked a Kevin McKernan long ball to the net to put Antrim ahead for the first time in the 48th minute and with Conor Johnston, Clarke, McKernan and Saul McCaughran among the scorers, they moved into a 1-18 to 1-11 advantage with a couple of minutes left.
Convery's injury-time goal cut Antrim's lead to four but the Saffrons still had time to respond with three more points.
Meanwhile, Down edged out Armagh 2-16 to 2-14 in the Division Two B Ulster derby at the Athletic Grounds.
Three Danny Toner points helped Down take a 0-6 to 0-3 lead but Armagh responded with an unanswered 1-3 which was highlighted by John Corvan's goal.
However, Toner's goal just before half-time contributed to Down taking a 1-9 to 1-8 lead at the break.
Points from Conor Woods, Caolan Bailie and Scott Nicholson helped Down move four clear before a Woods' sideline puck flew directly into the net in the 57th minute to extend the Mourne County's advantage to 2-14 to 1-10.
Helped by Corvan's goal, Armagh outscored Down 1-4 to 0-2 in the closing stages but it proved too late for the home side.

"How she lived is more important than how she died, and what she stood for is more important than the hatred that drove this act."
What, then, about the contrast between Jo's life, and that of her killer, Thomas Mair?
"He said I think, at the time, that he did what he did for Britain. But I think that Britain would be ashamed of him," Mr Cox said.
"I have no interest in him. I have some pity that his life was so devoid of love and so consumed with hatred that he thought this was an OK thing to do, but I have no interest in how he feels or what he thinks."
Mr Cox said he is not able to forgive the man who brutally murdered his wife.
"In order to talk about forgiveness you have to have some acceptance of how wrong and how evil what he did was, and I have seen no suggestion of any of that.
"From the way the trial was conducted, it feels like somebody who is both unbelievably cowardly and driven by hatred, but if those things were to change then it would be a different scenario.
"I think one of the reasons this happened was for a sense of notoriety and I don't want to bestow that," he added.
Although living in the aftermath of his wife's murder still feels "like a bad dream", Mr Cox said he and his two young children, aged four and five, find comfort in reminding themselves of the sort of person she was.
"Probably every other night, I ask people who knew Jo to write a story for the kids about something they did with Jo or a memory of Jo, and I'll read out one of those to the kids and they love them," he said.
"We have a lifetime of stories. Jo packed in probably 80 or 90 years into the 40 she lived.
"I'll remember her for her zest for life, an enthusiasm in almost all circumstances and about most things, an empathy towards other people and a love both of our family but also just of others."
Obituary: Proud Yorkshire lass Jo Cox
He said: "A lot of what Jo worked on was very worthy and important but she was also very mischievous and very fun and great just to play around with and to hang around with, so we'll remember all of that as well.
"When we were on the way to the funeral and there were thousands and thousands of people lining the streets of Batley, [their son] Cuillin said 'I knew people loved mum but I didn't know this many people loved her'."
"We talk about Jo every day, we talk about the things that made her amazing and we talk about the things that made her annoying... because that also made her so human and so endearing."
It is also through Mrs Cox's work as an MP that many people will remember her.
"She was driven by a very powerful sense of empathy and so when she would meet people who had a problem, she would be committed to dealing with that problem no matter how difficult or seemingly unsolvable," her husband said.
"I used to get very frustrated because every week when she would be up in the constituency at her surgery and she would call me up and say, 'I've missed the train again', and I would be very irritated.
"But she would say, 'it was because somebody turned up and their child support allowance hadn't come through and they didn't have any money for the weekend'. She had a very personal, human connection with people."
When asked how the family are trying to move forward with their lives, Mr Cox said one of the main things they want to achieve is to continue his wife's vision through the Jo Cox Foundation, which has raised more than Â£2m to help with issues such as loneliness, Syrian refugees, autism, and encouraging women in politics.
"For us this is the beginning of something," he said, explaining that their mission is to "make sure that in the years after, what's happened to Jo awakens something which is about bringing our communities back together".
"It's what she said, we do have more in common than that which divides us.
"We are in a place in the world where that message is even more necessary and Jo, if she was alive now, would be spending the vast majority of her time on making that case and that argument.
"She's not here, so we are going to do that in her name."

"Her voice has been strengthened by all this and not silenced," believes Brendan Cox, the husband of murdered MP Jo Cox.
