Born in Budapest, he studied under the direction of Imre Karoly Simay (born in 1874), a celebrated animal sculptor, painter and engraver in Hungary.
Kelety emigrated from Hungary to France after World War I and exposed a terra cotta bust executed by Arthur Goldscheider at the Salon des Artistes Decorateurs (Salon of Decorative Artists) in 1927.
His sculptures were exhibited in the stands of Goldscheider and of Etling at the Exposition of Modern Decorative and Industrial Arts in 1925.
Among his many bronze animal sculptures, he produced dramatic, sentimental and decorative representations. He sometimes mixed bronze and ivory, and sculpted in marble or other stones.
