These works solidified his reputation as a maestro of tango lyrics, capturing the essence of Buenos Aires.

In addition to his artistic achievements, González Castillo founded the University Popular de Boedo in 1928, fostering cultural education and artistic development. His contributions to cinema included scripts for silent films like "Nobleza Gaucha" (1915) and sound films such as "La Ley que Olvidaron" (1938).
