Samuel Dale (1659 – 18 March 1739) was an English naturalist and physician notable for his work in the natural sciences and his authorship of the Pharmacologia seu Manuductio ad Materiam Medicam in 1693.

It was in this position where Dale met and befriended John Ray, and began to assist him in his botanical work.

[1] While studying under Ray, Dale undertook regular excursions collecting plants for both his apothecary business, and for personal enjoyment.

[2] Dale also began authoring his own works, including Pharmacologia in 1693, which was a well received textbook of pharmacology and therapeutics.

Samuel Dale contributed nine papers to the Philosophical Transactions of the Royal Society including the first account of the strata and fossils of Harwich cliff.
