In 1912 his father disappeared, leaving Pigozzi, age 14, to take responsibility for his mother, his sister, and a small transport business.
In 1918, after the war, he secured the distribution rights for British and US motorcycles in the Piedmont region, selling surplus machines from the military stocks of the allied armies.
Between 1920 and 1922 he worked for a firm that imported coal from the Saarland.
In 1924 he set up his own business, importing scrap steel from France which was needed by the Piedmontese steel mills.
The principal customer for steel in the region was Fiat and in 1922 Pigozzi was introduced to Giovanni Agnelli, the owner of Fiat.
Agnelli was particularly interested in Pigozzi because at the time he was looking for a general commercial representative in France.
He ran Simca for nearly three decades, as Director General between 1935 and 1954 and as President-Director General between 1954 and 1963, which was when Chrysler, a minority share holder since buying 15% from Ford in 1958, increased their share-holding in the business to 64% and took control.
On 31 May 1963, with Chrysler in control, he was obliged to resign from the presidency of Simca.
According to his son Jean (see below), all three of Henri's children were borne by his mistress but raised by his wife, Loisette, as her own.
