Isaac Lawson (d. 1747), was a Scottish physician. He became a student of Leyden University on 17 May 1730. There he studied medicine and botany under Herman Boerhaave and Adriaan van Royen, and became the intimate friend of Linnaeus, whom he several times assisted with gifts of money. In conjunction with Jan Frederik Gronovius he was at the expense of the printing of the Systema Naturæ of Linnaeus in 1735. Lawson obtained his doctorate in medicine on December 28, 1737 in Leiden with a thesis on zinc oxide, his thesis being entitled Dissertatio Academica sistens Nihil.
