Robert Hooke observed the dead cells of the bark fr the first time but Antonie van Leeuwenhoek also observed the microorganism and made important contributions to the biology when he described the first living cell like amoeba and bark of an oak tree.

Thus, the first cell viewed by the light microscope was the cell of a bark of a tree.
