Ligeti initially studied under Alajos Stróbl in Budapest, and later in Paris, France and Vienna, Austria. His sculptures combined elements from impressionism and realism. His major works include: "Anonymus" (1903) in Budapest, the "Fountain of Peace", "Mrs. Dery", and the "Cavalry Artilleryman Memorial" (1937). Mrs. Dery and the Cavalry Memorial were heavily damaged in World War II and had to be removed. 

In 1911, he completed the 6 gigantic knights adorning the entrance to the Pavilion of Hungary for the Turin 1911 exposition.
