Giovanni Battista di Quadro
Giovanni Battista di Quadro (Polish Jan Baptysta Quadro, Latin Joannes Baptista Quadro) (died between 10 April 1590 and 16 January 1591) was a Polish-Swiss-Italian renaissance architect, one of the most famous architects in Central Europe in his epoque.
Until 1550 he probably worked in Saxony and Silesia, but in 13 March 1550 he signed a contract with the city council of Poznań for rebuilding the town hall. In 1551 with the agreement of the council he went to Płock as a consultant on the renovation of the cathedral. In the same year his name was mentioned in the court books of Poznań because of links between him and the Bishop of Poznań Benedykt Izdebski relating to building the bishop's palace in Krobia. From 1552 to 1562 di Quadro was the City Architect of Poznań, but the City Council paid him also in 1563, 1566, 1567 and 1570 for minor works. During these years, he worked for the citizens of Poznań and the clergy and nobles of Greater Poland.
His many well paid jobs made him wealthy. However, after he retired in 1573, he died as an indebted person in Poznań.
In years 1550-1552 in Poznań worked also his brothers Antoni, Gabriel and Kilian di Quadro.
