Bogdan Ivan Mandić was born May 12, 1866 in a coastal town of modern-day Montenegro (then the Austrian Empire). He was the 12th child of an owner of a fishing fleet. The family was ethnically Croat and from a noble family, through over time they lost their wealth. Bogdan was a sickly and malformed child, growing to only about 4’5”. He had a clumsy walk and a stutter. But that did not stop him from pursuing his education and dreams of becoming a priest.
There were Capuchin friars serving the community, and when Bogdan
was 16, he went to Italy to study and join their order. After two years, he was
admitted into the novitiate and given the name Leopold. He continued his
studies in Padua and Venice.
In 1890 he was ordained to the priesthood. He served in areas around northern Italy and Croatia as well as taught seminarians. In 1906 he was assigned to the friary in Padua where he spent the rest of his life. He was known as a sympathetic and compassionate confessor. He was also known for his work setting up orphanages and visiting the sick in the community.
