He was director of the Astronomical Observatory of Bologna from 1921 to 1954, with an interruption of over six years following the persecution for fascist racial laws. In 1931 he founded the magazine Coelum for the dissemination of astronomy in the society.[1]

In the thirties of the twentieth century, Guido Horn d 'Arturo was the creator of the tessellated telescope, progenitor of modern Multi Mirror Telescope.[2]

On the proposal of the Italian Astronomical Society, the National Institute for Astrophysics dedicated the telescope ASTRI (Astrophysics with Mirrors with Italian Replicant Technology), placed on volcano Etna in Sicily, to Horn. On 10 November 2018 with an official ceremony the telescope was name "ASTRI-Horn d'Arturo".

The asteroid 3744, discovered in 1983, bears the name "Horn-d'Arturo".
