    More Information:

    Toaldo (1719-98) "Priest and physicist, b. at Pianezze, 1719; d. at Padua, 1797. In his fourteenth year he entered the seminary of Padua, in which he subsequently taught mathematics and Italian literature. While connected with the seminary he edited the works of Galilei (1744), for which he wrote an appreciative preface and critical notes. In 1754 he was appointed pastor of Montegalda; and, eight years later, was called to the chair of astronomy in the University of Padua. Toaldo, like his contemporaries, Divisch and Beccaria (both priests), gave special attention to the study of atmospheric electricity and to the means of protecting buildings against lightning. He advocated the erection of lightning-rods, adopting the views of Franklin on their preventive and protective action, rather than those of the French school led by Abbe Nollet... through his exertions lightning-conductors were placed on the Cathedral of Siena, on the tower of St. Mark's, Venice, on powder magazines, and ships of the Venetian navy. Toaldo was a member of many of the learned bodies of Europe, notably of the Royal Society, London." [Catholic Ency.] "On the basis of meteorological data that had been collected in Padua over a period of forty-eight years, Toaldo claimed to have demonstrated that there was a relation between the electrical condition of the atmosphere and the growth of plants. Even more important, Toaldo claimed that he was on the verge of discovering a number of rules that seemed to make it possible to predict the weather on the basis of cyclical patterns. Toaldo's assumption that the weather would repeat itself in accordance with astronomical cycles was not new. However, his study was the first to appear to support this hypothesis with empirical data. This "discovery" of an astronomical-meteorological relationship boosted research into the occurrence of possible epidemic cycles. Within a short space of time, Toaldo's study was published in several languages and caused a sensation on a European scale." An eighteenth-century medical-meteorological society in the Netherlands..."[Huib  J . Z uidervaart. British Soc. for the Hist. of Science, Dec. 2005]
