Lia Comirato Dumas was the undisputed queen of the Mille Miglia, having entered the Italian classic eight times between 1936 and 1949.
Her best finish was second in 1948, driving a Fiat with her husband, Alberto. It was one of her last attempts at the race. They were also fourth in that year's Coppa d'Oro delle Dolomiti, in a Stanguellini.
The Comirato-Dumas’ first car was a Fiat Balilla 508C with berlinetta bodywork, built in 1935. It was a fairly modest car with a one-litre side-valve engine and 34 bhp. In their first Mille Miglia, they were fourteenth overall and second in the 1100cc class, behind the similar Fiat of Milton Biagini and Arcangelo Periccioli. The car was likely tuned and prepared by Fioravante Zanussi.
It was probably Alberto’s second Mille Miglia in the car, but Lia’s first time.
The same car and driver combination tackled the 1937 Miglia, but they did not finish for reasons unrecorded.
Lia’s next car was a modified Fiat 1100, called the “Fiat Comirato 1100”. This car was not successful in the Miglia either; it failed to finish in 1938 and 1940. Heavily customised with a narrower profile and less bodywork than a standard 1100; it was the subject of complaints by rival drivers who tried to claim it was illegal.
After the war, Alberto was the first to resume his motorsport career. He raced a Fiat 1100 in 1946, but Lia did not take the wheel herself. She returned in 1948 for another Mille Miglia, finishing eighth in another Comirato-built Fiat referred to as the “Fiat-Comirato Speciale.”
This new special was Lia’s car the 1949 Miglia, which she did not finish. The car was entered for the 1950 event, but did not make it to the start.
Her last Mille Miglia was the 1952 edition. She and Alberto drove a Siata Daina Gran Sport, another Fiat derivative. They were 66th and fifth in the 1500cc class.
Lia sometimes participated in other races in Italy, still driving with her husband. Between 1948 and 1950, the couple entered three editions of the Coppa d’Oro delle Dolomiti. The first two times, they drove the Stanguellini, in which they recorded a fourth place in 1948. In 1950, their car was another “Comirato Speciale”, based on an OSCA this time. It was entered by the OSCA team and they were seventh overall.
Earlier, in 1938, she may have driven with Alberto in the Targa Abruzzi, in a Fiat 1100.
The only time that Lia competed outside Italy was in the Litoranea Libica, a 1000km road race held in the Italian territory of Libya. She and Alberto were 16th in the first running of this event in 1937, driving a Fiat 500. The race was run a second time in 1939 and the couple entered again in a Fiat, but their finishing position is not known.
Much about Lia’s life and career is not known. Even her dates of birth and death are obscure. Alberto, although a more prolific racer, is scarcely better documented. He is known to have come from Treviso so it is likely that Lia was also from there, although “Dumas” as a name suggests French ancestry.
It is possible that Lia entered some of the women-only rallies and hillclimbs that seem to proliferate in Italy at the end of her career, but entry lists are hard to come by. She did not compete outside of Italian territory, so it is unlikely that she took part in the Paris-St. Raphaël Rally.
