(16 June 1640, in
Sainte-Olive
,
Ain
? 3 April 1718, in

) was a French
mathematician
.
Biography
[
edit
]
Jacques Ozanam was born in
Sainte-Olive
,
Ain
, France.
In 1670, he published trigonometric and
logarithmic
tables more accurate than the existing ones of
Ulacq
,
Pitiscus
, and
Briggs
. An act of kindness in lending money to two strangers brought him to the attention of M. d'Aguesseau, father of the chancellor, and he secured an invitation to settle in
Paris
. There he enjoyed prosperity and contentment for many years. He married, had a large family, and derived an ample income from teaching mathematics to private pupils, chiefly foreigners.
His mathematical publications were numerous and well received.
Recreations
(published 1694) was later translated into English and is well known today. He was elected a member of the
Academie des Sciences
in 1701. The death of his wife plunged him into deep sorrow, and the loss of his foreign pupils through the
War of the Spanish Succession
reduced him to poverty. He died in Paris on April 3, 1718 (frequently cited as 1717 because of an error in "eloge de Fontenelle").
Ozanam was honoured more abroad than at home. He was devout, charitable, courageous, and of simple faith. As a young man he had overcome a passion for gambling. He was wont to say that it was for the doctors of the
Sorbonne
to dispute, for the pope to decide, and for a mathematician to go to heaven in a perpendicular line.
He taught
Abraham de Moivre
.
