Alix was born and died in Paris. One of the specialists of his era in colour printing, he produced many illustrations of Parisian life and fashion of his own time along with many caricatures. He produced prints of
Voltaire,
Helvétius,
Buffon et
Jean-Jacques Rousseau (1791). He also produced images of figures from the French Revolution. For example, in 1789, he produced 18 prints of members of the
National Constituent Assembly, notably
Mirabeau, the
Abbé Grégoire,
Charles and
Alexandre de Lameth and
Antoine Barnave, published by Levacher de Charnois. He also produced printed portraits of
Jean-Paul Marat,
Pierre Louis Manuel,
Marie Joseph Chalier, general
Custine, general
Dumouriez Antoine Lavoisier and
Charlotte Corday. However, he was best known for his portraits of the child heroes
Joseph Bara and
Joseph Agricol Viala, whose distribution was largely funded and organised by the revolutionary propaganda machine. Under the
French Directory and
French Consulate, Alix turned especially towards historic subjects and subjects inspired by classical antiquity. He also produced prints of
Benjamin Franklin (1795), general
Hoche, general
Augereau (1797), general
Bonaparte at the head of the
armée d'Italie (1798), general
Kléber at the head of the
armée de Sambre-et-Meuse (1798), general
Berthier at the
pont de Lodi on 10 May 1796, general
Bernadotte,
Antoine-François Fourcroy (1802), Napoleon as First Consul (1803) and a group portrait of the three consuls (Bonaparte,
Cambacérès and
Lebrun). In 1815, on the
Second Restoration, he produced a print of
Louis XVIII after a painting by Pasquier and a ''The King's return on 8 July 1815'' after Martinet.
