Lajos Lencses was born in the small town of Dorog, Hungary. His first advanced studies were at the Budapest Academy of Music. Later on he studied at the Paris Conservatory of Music. Lencses gained his first important breakthrough when he captured first prize at the Geneva International Competition in 1968. He then launched his international career and was soon recognized as among the finest oboists in Europe.
He became a member of the Stuttgart Radio Orchestra and has served as the ensemble's principal oboist. By the 1980s Lencses was an active recording artist and in 1990 received the Diapason d'Or, the most prestigious French award given to a recording artist.
Throughout the 1990s and especially in the new century, Lencses remained busy in the recording studio, often focusing on the byways of the repertory (Franz Xaver Richter's F major Oboe Concerto, for example, on CPO from 1994) but also devoting attention to more mainstream offerings, like the 2003 Carus CD of the Mozart Concerto for Oboe in C major, K. 314. Among his later recordings is a 2007 Hänssler Classics release that is typical of his fearless nature to champion the unusual but worthy: the disc features oboe works by the little-known nineteenth century female composer Clémence de Grandval.
