Notes:
Ládiszlav "László" Hartmann was the son of a wealthy family from Budapest, Hungary, where he was born in 1901. Despite he didn't show proper aptitude behind the wheel of a car, he got his driving licence in his twenties and soon stared racing in minor events in the late 1920s, driving a Hupmobile. He participated in the Rallye Automobile de Monte-Carlo in 1930 with that car, finishing in 64th place overall, 16th in his class.

László Hartmann graduated to true racing cars, when he acquired from fellow-countryman Count Tivadar Zichy, a Bugatti T35B in which he took outright victories in Hungarian hillclimbs. He won five times the Guggerberg (between 1930 and 1933 and in 1935), twice the Hármashatár (1930 and 1935) and also the Parád-Gyöngyös (Mátra Hill) in 1930, the Gödöllõ in 1934 and the Feleac (Cluy-Brasov) in 1935. He finished second overall in the European Mountain Championship standings in 1930. László Hartmann progressed to a Bugatti T37A, then a 3-litre Maserati 8CM in which he became one of the most famous privateers in pre-war Grand Prix era.

Amongst his best international circuit racing results were his third place in the Grand Prix du Comminges at St. Gaudens, France, and a fourth place in the Grand Prix des Frontières, held on that incredibly fast circuit of Chimay, Belgium, in 1935. Two years later, Hartmann purchased a Maserati 6C-34, an ex-factory car formerly driven by the great Tazio Nuvolari. His remarkable results even prompted the Officine Maserati works team to send Hartmann a letter in which they thanked him for achieving successes with their car and to offer him a few drives as a semi-works entry. In 1937 a German magazine rated him as #13 amongst the European racing drivers. That year he finished sixth in the Internationales Avusrennen at the Berlin’s AVUS (Automobil-Verkehrs-und-Übungs-Straße), behind two Mercedes-Benz W125 - first with Hermann Lang - and three Auto Union Typ-C dominant cars. His final result came on 26 September 1937, when he finished a fine third in the voiturette Brno Grand Prix ("Velká cena města Brna") in a 1.5-litre Maserati 4CM, chassis #1550.

In 1938, László Hartmann and other 17 voiturette drivers were invited by the promoters of the Tripoli Grand Prix, scheduled to be held on Sunday, 15 May 1938, on the 13.1-kilometer (8.14-mile) Mellaha circuit near Tripoli in Libya then Italian colony, to complete the 30 cars grid, because they collected only 13 Grand Prix cars entries. The event, also called "The Race of Millions" was very important in Italy because there was a big lottery coupled with the Grand Prix, the first prize being 4 millions Italian Lire, something about actual 8 millions euro or U.S. dollars. 30 was the number of cars required for the lottery.

Hartmann set the ninth qualifying time in the voiturette class, starting from the sixth row in the grid. At the start of the race a number of Maserati voiturettes which were fielded behind the Grand Prix cars, dashed off mixed with the best competitors. Racing stars, including Hermann Lang who had won the pole position, Rudi Caracciola, Carlo Felice Trossi and others were trapped behind the voiturettes. Shortly later the big cars were able to go beyond leading the race, but other drivers got involved in the scrum. One of them, Giuseppe Farina at the wheel of a 3-litre Alfa Romeo 312 was making up for the delay, after a pit stop on the opening lap.

Farina reached László Hartmann to be lapped after 12 laps, near the “Torretta n. 3” on the slightly uphill part of the very fast circuit along the shoreline, between the third and fourth bends. Trying to overtake him, his right front wheel made contact with the left front wheel of Hartmann's Maserati and the two cars overturned. Hartmann ended in the cultivated field to the right, a few metres from track, his blue car with a tricolour flag on its tail came to rest with all four wheels in the air. A radiator and other wrecks of the cars hit a soldier and a spectator, Virgilio Scaglia and Francesco Verderame who suffered injuries. Farina came out of the accident virtually unscathed except for a few scratches, but László Hartmann who broke his spine, died the following day, Monday, 16 May 1938, in the Italian Hospital in Tripoli.

The official version put out at the end of the race, indicated that the impact between the two cars was caused by a gust of wind. But according to another version, supplied by a young lieutenant in the medical corps in charge as a medical officer near the place of accident, it would appear that Hartmann was not fast enough getting out the way and that Farina hit him and swept the car off the track. With his Red Cross team of volunteers, he was the first to reach Hartmann with his broken spine, and administered the first aid required in order to transport him to hospital, together with the other less serious victims of the crash.

Minutes before Hartmann's accident, another fatality marred the event, when Eugenio Siena crashed during the eighth lap of the race, being trown out of his Alfa Romeo. He died almost instantly.

After a ceremony during which the Italian General Pietro Badoglio held a speech over the two deceased drivers, Hartmann's corpse was transferred to Hungary by an Italian military plane and buried at the Rákoskeresztúr Cemetery in Budapest.
