Refer to the following passage and then answer the question later in the same language as the passage: Passage: Infinitesimal calculus was developed independently in the late 17th century by Isaac Newton and Gottfried Wilhelm Leibniz. Today, calculus has widespread uses in science, engineering, and economics. In mathematics education, calculus denotes courses in elementary mathematical analysis, which are primarily devoted to the study of functions and limits. The word calculus (plural calculi) is a Latin word, originally meaning "pebble" (this meaning is maintained in medicine, see Calculus (medicine)). Because such pebbles were used for calculation, the meaning of the word has evolved to mean the method of calculation. Therefore, it is used to name specific methods of calculus and related theories, such as propositional calculus, Ricci calculus, calculus of variations, lambda calculus, and process calculus. Question: Who developed infinitesimal calculus and when?<end_of_turn>
