Lazarus Leonard Aaronson MBE (24 December 1894 – 9 December 1966), often referred to as L. Aaronson, was a British poet and a lecturer in economics. 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. Though less radical in his use of language, he has been compared to his more renowned Whitechapel friend, Isaac Rosenberg, in terms of diction and verbal energy. 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.
