Toto Wolff has overseen all but one win by the mighty Mercedes AMG Petronas team since its debut in F1 in 2010, but one very special victorious Sunday stands apart from all the others in the Austrian's memory.
Wolff was called upon by Mercedes to run its works outfit in 2013, when the Austrian also became a 30% shareholder in the Brackley squad.
Since that year, Wolff has witnessed 115 victories and helped guide Mercedes to eight Constructors' championships and seven Drivers' titles, six of which were won by Lewis Hamilton.
But from the massive collection of memorable wins garnered over the years, Wolff's first home race at the Red Bull Ring in 2014, at the start of hybrid era when Mercedes had yet to impose its dominance on F1, holds a special place in his heart.
At the time, Wolff was still a shareholder of Williams, a team where he had been a director and for which his wife Susie was still a development driver.
Nico Rosberg and Hamilton delivered a one-two to Mercedes at the Austrian Grand Prix, which in itself was a reason for Wolff to rejoice. But with Valtteri Bottas and Felipe Massa finishing third and fourth for Williams, the Austrian's weekend was a clean sweep.

"I was still emotionally connected to Williams, Susie was part of the team and I think I even held some shares back then," Wolff remembered, speaking on a recent Beyond the Grid podcast.
"We finished first, second, third and fourth with Mercedes and Williams in a row, and as a co-owner of these two teams.
"I remember driving home on the same road that I used to commute on when I was an instructor at the racing school on the Red Bull [Ring], there was an unbelievable feeling of 'it can't possibly be happening'.
"That was in Formula 1, I'm responsible for the team and we just scored the first four positions [in a Grand Prix], it was a really happy moment.
"The dominance only lasts for a few hours. You collect the trophy and then the wheel continues to turn."
To this day, Wolff remains the team principal and a shareholder of the Mercedes outfit, the 50-year-old sharing an equal interest in the F1 outfit with chemical giant Ineos and Daimler.
In the past few seasons, Wolff has been considering his role in day-to-day control of the team, but the Austrian appears committed to keeping the reins of the team for the foreseeable future.
