Eugene Alexander von Nagy KOBZA [????-????]

He's mentioned as one of the three people involved in hiding the Chater collection in 1941:

     Shortly before Hong Kong was occupied by the Japanese in 1941, the Governor Sir Mark Aitchison Young ordered valuable works of Chater collection be hidden in the wine cellar and strong room in the basement of Government House. However the basement was considerably altered during the Japanese Occupation, the paintings were most probably discovered and removed by the Japanese troops. 

     There may be another secret store beside the basement. On December 8, 1941, Captain Batty-Smith, Aide-de-Camp to the Governor, had a secret meeting with von Kobza-nagy, a Hungarian expert and restorer, and Thomas Harmon of the Public Works Department. Later, documents reveal that valuable paintings of Chater Collection had their frames removed and then placed in sealed tins. They were buried in the garden of Government House. Only Batty-Smith, von Kobza-nagy and Thomas Harmon knew the exact location, but the mystery of the hidden paintings was buried after all three men died during the Japanese Occupation.
