His paternal grandfather Louis Antoine Deland was from Luxembourg and hairdresser to the queen, Sophia Magdalena of Denmark.
Pierre Deland was active as an interpreter, a private teacher, a clerk and an officer of the Livgardet before entering the stage profession in 1825, when he was engaged at the travelling theater of Carl Gustaf Bonuvier.
In 1831, he married the actress Charlotta de Broen, stepdaughter of Christoffer Svanberg and daughter of Isaac de Broen and Christina Margareta Cederberg, directors of the Djurgårdsteatern, and in 1833, he took over the travelling theater company of his wife's stepfather Christoffer Svanberg (thereby making it the Deland theater company).
He was considered a capable actor but, however, not one who kept himself updated, and reportedly, his success and popularity in the countryside caused him to stagnate somewhat during the latter part of the career, as he had become unaccustomed to criticism.
