Jiménez was part of the Chilean Literary Generation of the 1920 era that included Joaquín Cifuentes Sepúlveda, Armando Ulloa, Alejandro Vasquez, Rubén Azócar, Raimundo Echevarría Larrazabal, and Pablo Neruda.
His drawings influenced the aesthetic style of and contributed to the spread of painters and sculptors while he directed and collaborated with them for the newspaper Clarity (whose directors in its initial period were Raúl Silva Castro and Rafael Yepez).
There he, Paschin, and Magallanes Moure developed unusual trades, such as a cartoonist in bars and cafés or lender of a lens on the streets so that passersby could see the stars.
Sixty years later, Oreste Plath and the National Library published an autobiographical account and collection of his work, entitled Alberto Rojas Jiménez Walked Around Dawn, which may be downloaded in its original language.
