László, 7th Prince Batthyany-Strattmann (German: Ladislaus Batthyány-Strattmann; 28 October 1870 – 22 January 1931) was a Hungarian aristocrat and physician.

His childhood was marred by the fact that his father left his family and converted to Protestantism in order to marry another woman.

He studied agriculture at the Economic Academy of Vienna, later also a great number of other subjects, including chemistry, philosophy and music.

He met Countess Maria Theresia von Coreth zu Coredo und Starkenberg (1874-1951), a devout Catholic, daughter of Count Karl Theodor von Coreth zu Coredo und Starkenberg (1837-1894) and his wife, Anna Bogdanovna Pankratieva (1849-1912), member of the Russian nobility and niece of Nikita Pankratiev.

His wife organized the family's daily life, the children's education, and helped her husband in the hospital.

In 1902 Batthyány opened a private hospital with twenty-five beds next to it,[7] where he worked as a general practitioner, later specializing as a surgeon and oculist.

Pharmacists and opticians redeemed his prescriptions and prescribed glasses for free, as Doctor László settled the bill in one sum at the end of each month.

[5] From 1907 till his death, László Batthyány prayed the Little Office of the Blessed Virgin Mary in Latin every day, and the rosary in the evening.

[4] The beatification process was begun in 1944 as a joint effort of the Archbishop of Vienna (Austria) and the bishop of Szombathely (Hungary).
