In 1825, through an old army connection, baron Piotr Galichet, who had settled in Poland, he was hired by the government of the Kingdom of Poland to help develop a Polish textile industry. He became consultant to the Polish government, as well as the Bank of Poland. Because of the financial support of the latter, in 1831 he organized the first major factory of his project in Marymont near Warsaw. Two years later he was invited by relatives of Galichet, the Łubieński brothers with his business to their estate at Ruda Guzowska, where the factory had better prospects. Soon it became a great success and brought fame and prosperity both to the settlement and to Girard. In honour of Girard, Ruda Guzowska was renamed, "Żyrardów", a toponym derived of the polonised spelling of Girard's name.
