Old science fiction story about depositing a dollar in a bank and allowing the money to grow for 40 generations

"John Jones's Dollar", a short story by Harry Stephen Keeler, originally published in 1915, available at Project Gutenberg. The story is told in the form of a history lecture in the future:

On the 201st day of the year 3221 A.D., the professor of history at the University of Terra seated himself in front of the Visaphone and prepared to deliver the daily lecture to his class, the members of which resided in different portions of the earth.

"But to return to our subject. In the year 1921, one of these numerous John Joneses performed an apparently inconsequential action which caused the name of John Jones to go down in history. What did he do?

"He proceeded to one of these banks, known at that time as 'The First National Bank of Chicago,' and deposited there, one of these disks—a silver Dollar—to the credit of a certain individual. And this individual to whose credit the Dollar was deposited was no other person than the fortieth descendant of John Jones who stipulated in paper which was placed in the files of the bank, that the descendancy was to take place along the oldest child of each of the generations which would constitute his posterity.

"The bank accepted the Dollar under that understanding, together with another condition imposed by this John Jones, namely, that the interest was to be compounded annually. That meant that at the close of each year, the bank was to credit the account of John Jones's fortieth descendant with three one-hundredths of the account as it stood at the beginning of the year.

"History tells us little more concerning this John Jones—only that he died in the year 1931, or ten years afterward, leaving several children.

I'll throw out Mack Reynold's "Compound Interest". It was an answer to a previous question: What is this story about an investing time traveller?

I don't know about 40 generations, but the Futurama episode "A Fishful of Dollars" (S1 E6) contains this plotline:

As the crew scrounges up bail money, Fry notices that the bank where he used to have an account has remained in business. He still has his ATM card and remembers his PIN code: the price of a cheese pizza and large soda at Panucci's Pizza, where he used to work. The account had contained 93 cents in 1999, but after accruing interest at 2.25% per year for 1,000 years, the balance is now $4.3 billion.
