John James “Jack” McGrath (8 October 1919 – 6 November 1955) was an American racing driver and one of the standout figures of post-war Championship Car racing. A fierce competitor on both dirt and paved ovals, he became known as the “Splendid Splinter” and built a formidable reputation before his career was cut short in a fatal crash at the 1955 Bobby Ball Memorial.

Career
McGrath was born in Los Angeles, California, and grew up in nearby South Pasadena.
He first made his name in the booming Southern Californian midget and roadster scene of the late 1940s, becoming one of the major attractions at Gilmore Stadium in Los Angeles.
In 1946, McGrath won the inaugural California Roadster Association championship and earned the nickname “King of the Hot Rods”.
Alongside close friend and teammate Manuel Ayulo, he helped prove that the rough-and-ready track roadsters of the period could develop into serious competition machinery. By the early 1950s, those West Coast roadsters had evolved into the sprint cars that would become a cornerstone of American oval racing.
McGrath’s success soon carried him onto the national stage.
At AAA Championship Car level, he scored major victories in the 1951 Syracuse and Langhorne 100-mile races, won again at Syracuse in 1952 and added the Milwaukee 200 to his record in 1953.
Those results made him a genuine championship contender.
McGrath finished runner-up in the AAA National Championship in both 1952 and 1953, establishing himself as one of the strongest American open-wheel drivers of the era.
Indianapolis was naturally a major part of that reputation.
In the 1954 Indianapolis 500, McGrath led the opening 44 laps, showing that he possessed the speed to challenge at the front of America’s biggest race.
A year later, he was involved in one of the most memorable early exchanges of the 1955 Indianapolis 500.
McGrath and fellow Californian Bill Vukovich fought intensely for 26 laps, the pair trading the advantage in a race that was shaping up into a classic.
McGrath’s challenge ended on lap 54 when the magneto failed on the Offenhauser-powered Hinckle Special Kurtis 500C.
Only three laps later, tragedy struck.
Vukovich, then leading and chasing what would have been a third consecutive Indianapolis victory, was killed in a multi-car accident.
It was a grim afternoon even by the standards of an era in which motor racing remained extraordinarily dangerous.
McGrath continued competing through the 1955 season, but his own life would be lost just months later.
On 6 November, he entered the Bobby Ball Memorial at the Arizona State Fairgrounds in Phoenix, the final AAA dirt-track race of the season.
While negotiating Turn 3 on the one-mile dirt oval, McGrath lost control of his car. It crashed and overturned, killing him instantly.
He was 36 years old.
McGrath’s career lasted barely a decade at the highest levels, but it left a substantial mark. From winning the first CRA championship and helping shape the development of West Coast roadsters into sprint cars, to twice finishing second in the AAA National Championship and leading at Indianapolis, he was one of the defining American drivers of the early 1950s.
His story is also inseparable from the danger of that period. Fast, respected and successful, the “Splendid Splinter” became another of the era’s leading talents whose career ended far too soon.
