Aronson, known as "Jim" to his friends,[1] worked at several publications prior to founding the National Guardian.
[citation needed] Aronson founded the National Guardian in 1949 with John T. McManus and Cedric Belfrage.
Aronson also worked as a professor at Hunter College of the City University of New York.
In 1981 he was invited to mainland China to teach news-writing by the Chinese Academy of Social Sciences.
In China he found that the content and style were what the Maoist government wanted to change about Chinese journalism, not the purpose.
