Jean the Boilerman
Workman Tisserand until the thirty years age, Jean the Boilerman was a Autodidacte which acquired, during his free times, of great knowledge in Mathématiques and Astronomie. He calculated several eclipse S with much of exactitude and carried out excellent observations by means of instruments that one had provided him.
The astronomer Picardy Jean seeking somebody to continue the drafting of the Knowledge of times , a professor of the Collège of Lisieux in Paris recommended the Boilerman via to him Philippe of Hire. The Boilerman having calculated successfully a table of the passage of the the Moon by the Meridian , they made it come in 1680 to Paris where it was equipped with a pension of the Academy of Science.
It delivered astronomical tables considered then to represent the eclipses correctly solar and lunar and continued the drafting of the Connaissance of times . It could better calculate the eclipses that Hire with which it collaborated on a certain number of projects until the moment when it showed this last to have stolen the astronomical tables to him that it had published.
In the edition of 1701 of the Knowledge of times , the Boilerman was devoted to an attack in rule against Hire, attitude considered moved by the Academy of Science which required that the work be withdrawn from the sale, that it changes the foreword it and that it makes public excuses. The Boilerman was carried out on the first two points, but asserted health reasons at the time to come to excuse itself with the Academy. The president approved at the request of all the other academicians, Hire included, to exempt the Boilerman to ask forgiveness as a full assembly, but one excipa a payment requiring assiduity to stripe it nevertheless lists in 1702.
One supposes that it completed the five last years of its life in a store of precision instruments which it opened on the quay of the Clock, with the sign of the Two Earths.
Lalande said this business which “it made lose a useful astronomer for one which was not it”. Guillaume Amontons was of his pupils.
