As a young man, he belonged to a group of Jewish friends who are today known as the Whitechapel Boys, many of whom later achieved fame as writers and artists.

Aaronson's poetry is characterised more as 'post-Georgian' than modernistic, and reviewers have since been able to trace influences back to both the English poet John Keats, and Hebrew poets such as Shaul Tchernichovsky and Zalman Shneur.
