In 1840, he attended the landscape painting classes taught by Johann Wilhelm Schirmer at the Kunstakademie Düsseldorf.
In 1844 and 1847, together with August Leu [de] and Georg Saal, he visited Norway; painting a series of fjordscapes.
A meeting was arranged with Prince Albert, who purchased Becker's painting "The Jungfrau", as a gift for Queen Victoria.
He later toured Hungary (1876) and Romania (1882), where his visit was related to commissions he had received from the Hohenzollern-Sigmaringen family.
In October, 2002, a major retrospective of his works was held at the Kunst Archiv Darmstadt [de].
