Adriaan Vlacq

Adriaan Vlacq (1600–1667) was a Dutch book publisher and author of mathematical tables.

Born in Gouda, Vlacq published a table of logarithms from 1 to 100,000 to 10 decimal places in 1628 in his Arithmetica logarithmica.

This table was further extended by Jurij Vega in 1794, and by Alexander John Thompson in 1952.

A shorter trigonometric table called Canon Sinuum was included in later works of Vlacq.

[citation needed] The crater Vlacq on the Moon is named after him.
