Prati was born in Tenno, County of Tyrol and educated in Salzburg, Innsbruck, Vienna and Landshut. He trained in both medicine and in law, taking his law degree in Pavia in 1810. He moved to Milan to continue his studies where he became a Freemason and a Carbonaro. He practised law in Brescia and Trento but his clandestine activities came to the attention of the authorities and he fled to the safety of Switzerland in 1816. There he continued his political agitation, largely based in Chur and Yverdon.
He travelled throughout Europe, maintaining his revolutionary activism, before being granted right of asylum in England in 1823. There, he soon established a broad circle of exiled and radical friends including: Ugo Foscolo, Sir John Bowring, Thomas Campbell, Joseph Henry Green and Edward Craven Hawtrey. Though he claims that Bowring had introduced him to write for the Westminster Review, he managed a meagre living on various failed educational enterprises, and publishing on educational matters and tutoring in German. He was imprisoned for debt in 1829 and took the opportunity to learn English medical terminology under the guidance of Green.
Returning to England in 1831 he joined the Friends of the People Society and professed to be a Saint-Simonian. He then took up the practice of medicine, contributing a medical column to the radical Penny Satirist from 1837 to 1840, in addition to editing the magazine.
