Later he studied and worked in Italy and France, and eventually he moved to Britain in 1935 after being commissioned to record King George V's silver jubilee. He opened a studio near Waterloo Station, which later became an exhibition and then a cafe-bar featuring his art.
He married twice, first to Marian Everall and then Caryl J. Stanley.
During the Second World War, Topolski became an official war artist and painted scenes of the Battle of Britain and other battlefields. In 1941, Topolski travelled to Russia alongside the men of 151 Wing RAF on board the RMS Llanstephan Castle, which was sailing to the port Archangelsk as part of Force Benedict, a mission to provide air support in defence of the port of Murmansk. Topolski was travelling as an accredited War Artist for both Polish and British Governments. He was also under contract to Picture Post magazine, which published many of his drawings after his return.
Feliks Topolski’s experiences were initially captured in pencil and ink drawings. These were the first stage of his prolific Chronicles, which appeared fortnightly from 1953 to 1979, interrupted only to accommodate his exploratory investigations across the globe. The Chronicles communicated his art and observations to a wider audience. They were independently published, without advertisements or subsidies. Since his death in 1989 Topolski’s Chronicles have retained respect as a pictorial and political record spanning nearly thirty years of world history. The Chronicles contain 3,000 drawings, and were exhibited in New York, Moscow, Cologne, Hamburg, Hawaii, Tel Aviv and serialised in the United States, Poland, Italy, Denmark and Switzerland. As Joyce Carey wrote, it is ‘the most brilliant record we have of the contemporary scene as seized by a contemporary mind.’
In 1959, Prince Philip, Duke of Edinburgh commissioned Topolski to create a mural depicting the coronation of Queen Elizabeth II. The mural contains 14 friezes divided into two narratives; one narrative; entitled 'In The Streets' shows various processions to Westminster Abbey, while the second, enititled 'In The Abbey', depicts the procession out of the Abbey after the coronation.
Topolski painted portraits of contemporaries, including the authors H.G. Wells, Graham Greene, John Mortimer and Evelyn Waugh, and politicians Harold Macmillan and Aneurin Bevan, He also painted murals, contributed to BBC programmes, such as the caricatures of guests used in Face to Face and designed theatrical sets. Between 1975 and his death he worked on a 600 ft mural in a studio in railway arches near London's South Bank, depicting events and people of the 20th century. It opened to the public as a free permanent exhibition called Topolski Century. In 2014 it was re-opened as a cafe-bar called Topolski, featuring his art.
In 1989 he was elected a senior Royal Academician as a draughtsman.
