From the volume:
Further information about the artist from the Imperial War Museum:Viktor Olgyai studied under William Unger in Vienna and under Theodore Alphonse in Paris. As he originally intended to devote himself entirely to the graphic arts, and only later took up oil-painting, his technical knowledge of etching is remarkable. He is pre-eminently a draughtsman, and though his plates are finely toned, the most notable thing about them is their sense of line. Some of his best works are contained in an album of ten plates entitle 'Winter,' and other notable ones are The Oak, The Mill and Way of Cypresses.
Victor Olgyai (1870-1929) was born in Igló in Hungary. He worked as a painter and designer, and taught at the Graphics Department of the College of Fine Arts in Budapest. He died in Salzburg, Austria.
