Lüdig is considered one of the major organisers of large-scale musical events in 20th century Estonia.
He was born in Vaskrääma, studied at both Moscow and St. Petersburg conservatories, and was a student of Nicolai Soloviev.
Lüdig initiated and led a number of events: Lüdig was among the founders of Esto-Muusika, the most successful music supply business in Estonia of the time, and the short-lived monthly journal Helikund [et], edited by Eduard Visnapuu [et].
However, the rumours of lack of organists in Buenos Aires turned out to be severely overblown, so his career there began at the post of an inn pianist; later he also conducted for a local German male choir.
His son Peeter Paul Lüdig (1906 - 1983), who was a pianist, organist and conductor, also left in 1939 for Germany, later he also lived in the USA.
