Theo kept all of Vincent's letters to him; Vincent kept few of the letters he received. After both had died, Theo's widow Johanna arranged for the publication of some of their letters. A few appeared in 1906 and 1913; the majority were published in 1914. Vincent's letters are eloquent and expressive and have been described as having a "diary-like intimacy", and read in parts like autobiography. The translator Arnold Pomerans wrote that their publication adds a "fresh dimension to the understanding of Van Gogh's artistic achievement, an understanding granted us by virtually no other painter".
In July 1869 Van Gogh's uncle Cent obtained a position for him at the art dealers Goupil & Cie in The Hague. After completing his training in 1873, he was transferred to Goupil's London branch at Southampton Street, and took lodgings at 87 Hackford Road, Stockwell. This was a happy time for Van Gogh; he was successful at work, and at 20 was earning more than his father. Theo's wife later remarked that this was the best year of Vincent's life. He became infatuated with his landlady's daughter, Eugénie Loyer, but was rejected after confessing his feelings; she was secretly engaged to a former lodger. He grew more isolated, and religiously fervent. His father and uncle arranged a transfer to Paris in 1875, where he became resentful of issues such as the degree to which the firm commodified art, and was dismissed a year later.
In November 1959, Van Dyke made his Broadway debut in The Girls Against the Boys. He then played the lead role of Albert Peterson in Bye Bye Birdie, which ran from April 14, 1960, to October 7, 1961. In a May 2011 interview with Rachael Ray, Van Dyke said that when he auditioned for a smaller part in the show he had no experience as a dancer, and that after he sang his audition song he did an impromptu soft-shoe out of sheer nervousness. Gower Champion, the show's director and choreographer, was watching, and promptly went up on stage to inform Van Dyke he had the lead. An astonished Van Dyke protested that he could not dance, to which Champion replied: "We'll teach you". That musical won four Tony awards including Van Dyke's Best Featured Actor Tony, in 1961. In 1980, Van Dyke appeared as the title role in the first Broadway revival of The Music Man.
