Robert Hooke called Leeuwenhoek the microscope's "single votary"

February 1, 1692

Robert Hooke, in a lecture titled "Discourse concerning Telescopes and Microscopes", called Leeuwenhoek the microscope's “single votary, … besides whom none make any other use of that instrument.”

In a review in Philosophical Experiments and Observations (p, 270), Richard Waller reported the lecture as being delivered on November 29, 1693. However, the title itself includes the date of February 1691/2.

In Fabric of Life, p. 45, Marian Fournier provided a chart illustrating this claim:

It is also clear that, from 1685 until his death in 1723, Leeuwenhoek alone accounted for about three-quarters of the total production in this specialized branch of scientific activity.
