[2] He was the second of six children and the eldest son (his twin brother died at birth) of his parents, Barnett (formerly Dovber) and Hacha Rosenberg, who were Lithuanian Jewish immigrants to Britain from Dvinsk (now in Latvia).

[1] Isaac Rosenberg attended St. Paul's Primary School at Wellclose Square, St George in the East parish.

He withdrew from his apprenticeship in January 1911, as he had managed to find the finances to attend the Slade School of Fine Art at University College, London (UCL).

[4] During his time at Slade School, Rosenberg notably studied alongside David Bomberg, Mark Gertler, Stanley Spencer, Paul Nash, Edward Wadsworth, Dora Carrington, William Roberts, and Christopher Nevinson.

Afraid that his chronic bronchitis would worsen, Rosenberg hoped to cure himself by relocating in 1914 to the warmer climate of South Africa, where his sister Mina lived in Cape Town.

[3] He published a second collection of poems, Youth and then after being unable to find a permanent job enlisted in the British Army at the end of October 1915.

[3] In January 1917, Rosenberg reported being sick and his family and friends asked his superiors to remove him from the front lines; he was transferred to the Fortieth Division Works Battalion and started to deliver barbed wire to the trenches.

He was first buried in a mass grave, but in 1926 the unidentified remains of the six KORL soldiers were individually re-interred at Bailleul Road East Cemetery, Plot V, Saint-Laurent-Blangy, Pas de Calais, France.
