Sir Dinshaw Maneckji Petit, 1st Baronet (30 June 1823 – 5 May 1901) was an Indian industrialist and philanthropist who founded the first textile mills in India.

Fali’s sister, Ratanbai Petit was the wife of the founder of Pakistan, Muhammad Ali Jinnah.

[4] The case of Dinsaw Maneckjee Petit is one of the few occasions where the government has seen fit to lift the corporate veil, due to the egregious nature of the tax avoidance.

[5] As broker to European firms, Petit amassed a large fortune during the period of speculation in Bombay at the time of the American Civil War.

The fund succeeded in convincing a number of Iranian Zoroastrians to migrate to India (where they are today known as Iranis), and may have been instrumental in obtaining a remission of the jizya poll tax for their co-religionists in 1882.

By Special Act of the Legislative Council of India, all holders of the title were to relinquish their own name on succession and assume those of the first Baronet.
