[3][4] He exhibited his first works as early as 1881, and showed at the Royal Academy, the New Gallery, and the Society of British Artists.

[1] Some other Solomon paintings that have received significant attention include Ajax and Cassandra (1886) and The Birth of Love (1896).

[1] Solomon became well known as an innovative portrait artist by the time he painted Mrs Patrick Campbell as 'Paula Tanqueray' ARA (1894),[3] her role in Arthur Wing Pinero's The Second Mrs Tanqueray, and went on to paint a number of portraits of well-known people, including the architect Sir Aston Webb, and later in life, the royals King George V, Queen Mary, and Prince Edward (later King Edward VIII).

Having originally signed-up at the start of the war as a private in The Artists Rifles, a Territorial Force regiment, he promoted his ideas on camouflage, initially in the press and then directly to senior army officers.

[9] In December 1915, General Herbert Plumer arranged for Solomon to visit the front lines and investigate techniques in use by the French.

His ideas were accepted, and he was asked to set up a team to start the production of camouflage materials in France.

[10] On 31 December 1915, General Douglas Haig, Commander-in-chief of the British forces in France, instructed that Solomon be given the temporary rank of Lieutenant-Colonel to enable him to carry out his new duties.

[12] Eventually, in 1920, he published a book, Strategic Camouflage, arguing this case, to critical derision in England but with some support from German newspapers.

[12] Solomon's daughter, Iris, was married to Ewen Montagu, one of the "brains" behind Operation Mincemeat in World War Two.
