Die Schwalbe, Issue 311, October 2021 wrote about him:

"Tivadar Kardos (26.9.1921-15.5.1998) was a very active problemist from 1942 onwards - the PDB alone contains 1480 problems by him. In addition to composition, he also compiled several problem collections, which he used to write many articles in which certain topics were systematically treated. He was head of the problem section of the journal Budapesti Sakkhiradó and edited the journal Feladvány-kedvelök lapja from 1969 to 1975 (even in the years of publication of this journal it was a challenge to pronounce its name without dropping it)."
