Franzin arrived in Brazil in 1887, going to work on a farm called "Recreio", owned by João Rezende da Cruz; just a year later Franzin would run other farms, like Santa Rita, Santa Eulália and Rosário. After many years of work, he purchased land with his brother Jácomo and decided to try coffee planting. The first properties they acquired were the farms Palmeiras and Limoeiro, followed by the lands of Floresta Escura, Gonçalves, Tuncum and Araquá, as well as houses, lots, and two machines to process coffee beans. Search for oil and the discovery of springs In the 1920s Júlio Prestes, the governor of São Paulo, began exploration of the oil prospecting area in São Pedro. His efforts failed to find petroleum, and the equipment was abandoned, but still gushing out mineral water. Subsequently, other attempts were made to find oil at greater depths, and again no oil was found. One oil rig structure still remains; it is called the Torre de Petróleo Engenheiro Ângelo Balloni (Engineer Ângelo Balloni Oil Tower). Years later, in 1934, Franzin, owner of some of the land in the area, built a simple bath house (currently known as the "Youth Fountain") in one of the springs where he bathed, the waters of which had a characteristic smell of sulfur. A year later, a group of townspeople bought a lot measuring around the original wood bath house, where they built a health resort. It was composed of twelve masonry bathtubs. In that same year, Octavio Moura Andrade decided to build a spa there, giving it the name of Caldas de São Pedro, and, along with his brother, Antonio Joaquim de Moura Andrade, established the company Águas Sulfídricas e Termais de São Pedro S.A. (Saint Peter Thermal and Sulphydric Waters S.A.). For four years, the Institute for Technological Research (IPT) of the University of São Paulo conducted a series of studies of those waters. Generally, water from great depths has a high concentration of substances that may be harmful to human beings, and its pH may not be suitable for bathing. In 1940 the results were published in Bulletin 26 of the IPT. The waters were deemed good for bathing, and their medicinal properties were studied by Professor João de Aguiar Pupo, Dean of the Faculty of Medicine of São Paulo.
