The word stockholder once meant something literal: the person who held the longer half of a split wooden stick. This episode follows the tally stick from prehistoric notched bones to the medieval English Exchequer, where a length of squared hazelwood became an unforgeable receipt. Notches were cut across the stick to record a debt, then the wood was split lengthwise through the marks. The lender kept the stock, the borrower kept the shorter foil, and because no two pieces of wood splinter the same way, only the original halves would ever fit together again.

Around 1100, King Henry I brought the system into the Exchequer to record tax payments, and the sticks began to circulate as money. Kings issued tallies against taxes they had not yet collected, and tallies later helped capitalize the Bank of England. The story ends in 1834, when officials fed six centuries of obsolete sticks into furnaces beneath the House of Lords and set the Palace of Westminster ablaze.

• The Lebombo bone, a baboon fibula with 29 notches found in Eswatini, dates back roughly 43,000 to 44,000 years and ranks among the oldest known counting tools.
• Exchequer cuts were standardized by the body and the farm: a palm’s thickness meant 1,000 pounds, a thumb’s breadth 100 pounds, a little finger 20 pounds, and a swollen barley grain one pound.
• Merchants accepted tax tallies as payment at a slight discount, turning wooden receipts into a circulating currency and letting the Crown spend against future revenue.
• In 1697 investors bought one million pounds of Bank of England stock using 800,000 pounds in tally sticks and 200,000 pounds in paper notes.
• Article 1333 of the 1804 Napoleonic Code recognized tallies as legal proof, and Charles Dickens mocked the 1834 fire in 1855 as a monument to bureaucratic routine.
