a year's compulsory military service. The lengthy downtimes enabled him to complete a commission to translate four essays from John Stuart Mill's collected works. He graduated with an MD in March 1881. Early career and marriage In 1882, Freud began his medical career at Vienna General Hospital. His research work in cerebral anatomy led to the publication in 1884 of an influential paper on the palliative effects of cocaine, and his work on aphasia would form the basis of his first book On Aphasia: A Critical Study, published in 1891. Over a three-year period, Freud worked in various departments of the hospital. His time spent in Theodor Meynert's psychiatric clinic and as a locum in a local asylum led to an increased interest in clinical work. His substantial body of published research led to his appointment as a university lecturer or docent in neuropathology in 1885, a non-salaried post but one which entitled him to give lectures at the University of Vienna. In 1886, Freud resigned his hospital post and entered private practice specializing in "nervous disorders". The same year he married Martha Bernays, the granddaughter of Isaac Bernays, a chief rabbi in Hamburg. Freud was, as an atheist, dismayed at the requirement in Austria for a Jewish religious ceremony and briefly considered, before dismissing, the prospect of joining the Protestant 'Confession' to avoid one. In the event a civil ceremony took place on 13 September and a religious ceremony the following day with Freud having been hastily tutored in the Hebrew prayers. The Freuds had six children: Mathilde (b. 1887), Jean-Martin (b. 1889), Oliver (b. 1891), Ernst (b. 1892), Sophie (b. 1893), and Anna (b. 1895). From 1891 until they left Vienna in 1938, Freud and his family lived in an apartment at Berggasse 19, near Innere Stadt, a historical district of Vienna. In 1896, Minna Bernays, Martha Freud's sister, became a permanent member of the Freud household after the death of her fiancé. The close relationship she formed with Freud led to rumours, started by Carl Jung, of an affair. The discovery of a Swiss hotel guest-book entry for 13 August 1898, signed by Freud whilst travelling with his sister-in-law, has been presented as evidence of the affair. Freud began smoking tobacco at age 24; initially a cigarette smoker, he became a cigar smoker. He believed smoking enhanced his capacity to work and that he could exercise self-control
