Lucien Voigt is Jude’s boss at Rosen Pritchard and Klein, one of the city’s most important firms. He’s always impressed with Jude’s work, though he also urges Jude to take some time off when it’s clear that Jude is working too hard (or using work to distract himself from other aspects of his life). Jude accepts Lucien’s job offer after a particularly frightening health scare makes him realize that he’ll need to have a lot of money to afford good, dignified care as his condition worsens later in life. Jude tries to hide as much of his disability and personal struggles (and personal life, for that matter) from his colleagues as he can, but Lucien comes to Jude’s aid when a janitor stumbles upon Jude in the midst of an episode late at the office one night. Lucien is one of the few characters in the novel who lives to old age, but his longevity isn’t devoid of suffering: Lucien suffers a massive stroke that greatly impacts his physical and cognitive abilities, greatly diminishing his quality of life. Jude regularly visits Lucien in the years after Willem’s death.
