In 2014, which three time Formula One World Drivers Champion passed away and was remembered as a pioneering driver, team owner and constructor?

Introduction / Context:
This question relates to sports, specifically Formula One motor racing. It asks about a legendary three time World Drivers Champion who died in 2014 and who was also noted for being both a driver and a constructor. Knowing major champions and milestones in Formula One is a common requirement in sports general knowledge sections.

Given Data / Assumptions:

• The person was a Formula One driver.
• He won the World Drivers Championship three times.
• He passed away in 2014.
• He is remembered as a pioneering driver, team owner and constructor.

Concept / Approach:
Sir Jack Brabham from Australia is a key figure in Formula One history. He won the World Drivers Championship in 1959, 1960 and 1966. He is unique because he won one of those titles while driving a car built by his own team, Brabham, making him both driver and constructor champion. Sir Jack Brabham died in May 2014. Other legendary drivers like Niki Lauda, Sir Jackie Stewart, Alain Prost and Nelson Piquet have impressive records but do not match all of these specific details, especially the 2014 date and the combination of roles.

Step-by-Step Solution:
Step 1: Focus on the combination of clues: three titles, role as driver constructor and the year of death, 2014. Step 2: Recall that Sir Jack Brabham won three championships and later founded his own team, becoming the only driver to win a world title in a car bearing his own name. Step 3: Note that he passed away in 2014, which is widely reported in sports news archives. Step 4: Compare this with Niki Lauda, who also won three titles but died later, in 2019, and is not primarily known as a constructor champion. Step 5: Sir Jackie Stewart won three titles as well but did not die in 2014 and is not a constructor in the same sense. Step 6: Alain Prost and Nelson Piquet each have multiple championships but their careers and dates do not match the death in 2014. Step 7: Therefore Sir Jack Brabham is the only option that fits all the conditions.

Verification / Alternative check:
An alternative check is to consult lists of Formula One World Drivers Champions and their years of death. These will show that Sir Jack Brabham, a three time champion and founder of the Brabham team, died in May 2014. Articles remembering his career highlight his pioneering role as a driver constructor and his influence on the sport, which matches the description in the question.

Why Other Options Are Wrong:
Niki Lauda was a three time champion but passed away in 2019, not 2014. Sir Jackie Stewart is a living legend and did not die in 2014. Alain Prost has four world titles, not three, and is still alive. Nelson Piquet has three titles but is also alive and is not primarily remembered as a constructor.

Common Pitfalls:
Many candidates know that Niki Lauda, Sir Jackie Stewart and others are multiple time champions and may select them without checking the year of death. Another confusion is assuming that any famous champion might have been a constructor as well. Reading the full set of clues carefully and matching them to a specific individual avoids these mistakes.

Final Answer:
The three time Formula One World Drivers Champion who passed away in 2014 was Sir Jack Brabham.
