Dr. Ludmány was born and raised in Debrecen, the second-largest city in Hungary. He graduated in physics from Kossuth Lajos University (now the University of Debrecen), after which he began working as a young researcher at the Heliophysical Observatory in Debrecen. He earned his PhD in 1991 from the Kyiv Astronomical Observatory of the Ukraine Academy of Sciences.
His entire scientific career was spent at the Debrecen Heliophysical Observatory, where his work focused mainly on the dynamics of solar active regions, solar flares, and solar-terrestrial physics. After 1976, when the observatory took over responsibility for continuing the Greenwich Photoheliographic Results sunspot catalog, he became deeply involved in the sunspot databases together with his wife and colleague, Dr. Tünde Baranyi. He remained actively engaged in observation and research even during his leadership, up to his retirement in 2015. After his retirement, he was awarded an international grant together with his wife, and worked on the implementation of the project. Following her death in 2018, he continued his scientific work with remarkable dedication and brought the project to completion. In his later years, he remained actively engaged in the continuation of the well-known Debrecen sunspot catalog, which was discontinued in 2018.
Beyond his dedication to science, he had a deep love of classical music. He played the piano, the organ, and the flute, and in his earlier years he also sang in a choir. At the University of Debrecen, he taught not only solar and space physics to future physicists but also acoustics to aspiring musicians.
András is survived by his two daughters, Orsolya and Fruzsina, and his son, Bence.
