Prince Birabongse Bhanudej Bhanubandh (15 July 1914 – 23 December 1985), better known as Prince Bira of Siam (now Thailand) or by his nom de course B. Bira, was a member of the Thai royal family, racing driver, sailor, and pilot. Birabongse raced in Formula One and Grand Prix races for the Maserati, Gordini, and Connaught teams. He was the only Southeast Asian driver to compete in Formula One until Malaysia's Alex Yoong joined Minardi in 2001, as well as the only Thai driver to compete in Formula One until Alexander Albon made his debut in 2019.
Bira first raced with his cousin Prince Chula's team, White Mouse Racing, driving a Riley Imp at Brooklands in 1935. In this car Bira established the national motor racing colours of Siam: pale blue with yellow. Bira blue was to be become the staple livery of the Whitemouse Garage cars. Chula and Bira also decided to paint two national flags on the bonnet of their cars: The Union Jack on the right side, the side of honor, to represent the manufacturers. The Siamese flag on the left side, to represent the driver. After the war, Bira returned to racing with several teams. The origin of the white mouse can be traced to Chula's nickname: Nou. In Siamese, 'Nou' means little mouse. Bira painted a white mouse on all his cars to signify his cousin's involvement in all his racing activities.
In 1951 Prince Bira created his own team: Ecurie Siam. He raced in an old Maserati 4CLT fitted with a newer V12 Osca engine at Spanish GP. Starting in 19th, the race lasted only 1 lap due to engine problems.
