The jury of the “Grosse Berliner Kunstausstellung” (great Berlin art exhibition) disapproved however the exhibition of his paintings. Hendrich then started a job as painter in Amsterdam. In 1882, he married Clara (Kläre) Becker which he met there. On their honeymoon trip they visited Hendrich’s brother in Auburn, New York. Here, he exhibited for the first time his paintings. After some initial sales, the remaining entire amount of pictures was bought by a single art dealer. Using the earned money Hendrich then made a study trip through the USA.
