The dominant use of compound microscopes over the following centuries meant that the brief blaze of Leeuwenhoek's discoveries was nearly extinguished until the great compound microscope makers of the early-nineteenth century, notably Joseph Bancks who also produced some high-powered single-lens microscopes, used by Robert Brown in his discovery of Brownian motion and cytoplasmic streaming, and by Darwin aboard the Beagle.
