[1] Schönberg was of military age and served as a soldier in the Austrian army and fought in the Battle of Custoza (1866) as part of the Third Italian War of Independence.

[4] In 1901, when Schönberg was in China, the census shows Pauline was staying with a cousin in Ernst Carl Fuchs at Penge in Kent.

By the 1911 census, the couple, now in their 60s were boarding with the Bruck brothers, Walter, a fine art publisher, and William, a process engraver, in Weylands, 21, Southend Road, Beckham.

Wurzbach noted that Schönberg's sketches were well drawn, gave a faithful rendering of the scenes, and when many people were represented, the groups were cleverly distributed and the timing of the drawing chosen with a lucid eye.

It was a long drawn out process as he first had to produce watercolour sketches and mid-sized oil paintings to get approval for the large-scale oil-paintings.

[8] Schönberg provided illustrations for many publications, starting in his native Austria and then moving further afield to Germany, France, and England.

Schönberg was a correspondent as well as an artist and sent reports and conducted interviews, in addition to sending sketches of the action or of the aftermath of war.

Schönberg did twelve full-page illustrations as line-and-wash drawings reproduced by black line and sepia tint plates.

[11]: 130  Newbolt notes that Schönberg's work was limited by the quality of available processes and sometimes by the printer's choice of cheap paper.

This time it was In the Reign of Terror: The Adventures of a Westminster Boy, (1888), London, Blackie, a story about the French Revolution.
