James Whatman was born into a family of tanners based around Kent, England in 1907. Whatman learned the tanners trade, but, as the tanning process produced a gelatin by-product used by paper makers, Whatman was in close contact with paper makers, and notably the Harris family. In 1733, Whatman built a paper mill for his friend, Richard Harris.
