Life

He was originally of Flemish ethnicity from Gouda, Holland.[2]

He filled up the gap in the numbers between 20,000 and 90,000 in the logarithmic tables.[2]

The logarithmic tables produced by Ulacq proved to be extremely useful for land surveyors.

Honours

His achievements in logarithms and mathematics have been noted by several authors and sources.

These include the Lexicon Technicum.[4]

It also includes Diderot's Encyclopédie.[5]
