Oliver Pollock: The New Orleans Merchant Who Paid for the War in the West
You'll be able to
- Trace Pollock from Ulster and Philadelphia to Havana and New Orleans
- Explain how bills of exchange let him finance Clark and why he was left holding the debt
- Compare the sources on his repayment, since they disagree on dates and amounts
- Judge the claim that he invented the dollar sign
In 1792, the National Archives says, the United States paid Oliver Pollock $108,605.02.1 It was a lot of money, and it came about a decade late. Pollock had spent the war signing his name to paper so that other men could buy powder, boats and flour in the West. When the paper came due, his name was the one on it.
A Philadelphia Merchant in Spanish New Orleans
Pollock was an Irish immigrant, born about 1737, and the sources do not agree on where. Wikipedia names Bready, County Tyrone. 64 Parishes names Coleraine. The Clements Library finding aid says near the parish of Donagheady.234 He came to Pennsylvania in 1760 and settled near Carlisle. 64 Parishes says he joined the Philadelphia firm of Willing and Morris and that it sent him to Havana in 1762 to sell supplies to the British army.3 There he met Alejandro O'Reilly, a general in Spanish service.
The National Archives says Pollock moved to New Orleans in 1768, in the turmoil of the change from French to Spanish rule. 64 Parishes and the Clements Library say 1769, when O'Reilly came to New Orleans and Pollock followed soon after.134 Either way, Pollock got there with flour in a time of hunger, and O'Reilly rewarded him with free trading rights.1 He built an indigo plantation at Tunica Bend. He also invested in the slave trade, as 64 Parishes plainly says.3
Powder, Willing and Galvez
When the war began, a merchant with Pollock's connections was worth more than a regiment. In September 1776 he helped a Virginia officer, George Gibson, arrange gunpowder shipments from Spain. The Clements Library says Congress appointed him its commercial agent at New Orleans in 1777. 64 Parishes has Congress and then Virginia naming him their agent in 1778.34
In 1778 he found safe harbor for his former business partner James Willing, who had raided British plantations in West Florida. With the permission of the Spanish governor, Bernardo de Galvez, Pollock sold the spoils of Willing's first expedition, 85 enslaved men and women. The sale raised enough money that he refitted a captured British ship for slave raiding.3 Part of the money behind the American cause on the Gulf came from selling people.
Atlas Obscura says Pollock personally convinced Galvez that Washington could win the war, and that he raised troops and supplies for Galvez's campaign against the British forts on the Mississippi. It says that effort drained his own fortune too.5 Wikipedia says Pollock borrowed $70,000 from Galvez in 1778. 64 Parishes puts the loan at $74,000 and places it in the years after his money ran short in 1779.23
Clark's Paymaster
The National Archives says Pollock "almost single-handedly bankrolled" George Rogers Clark's campaign in the Illinois country.1 The tool was the bill of exchange. Clark's associates drew on Pollock's account, Pollock honored the drafts, and Virginia and Congress were supposed to make him whole. Atlas Obscura adds that Governor Thomas Jefferson publicly backed Pollock, which helped buyers trust the paper.5
The trouble was that Clark's men kept drawing. 64 Parishes says they misjudged how much Pollock could cover and overdrew his accounts, and a bill of $237,320 from Clark's Fort Jefferson in January 1782 was the last straw.6 Neither Virginia nor Congress paid in time, and Pollock, the National Archives says, became the liable party. Creditors came for him.1
Jail in Havana and Slow Repayment
He declared bankruptcy in 1782. In 1783 the United States named him its agent in Havana, but his creditors there put him in a debtors' prison for more than a year until Galvez bailed him out. The National Archives says Galvez's certificate of May 1785 gave a figure of $79,087 and praised Pollock's service. Wikipedia and Atlas Obscura put the debt that jailed him at about $150,000, so the numbers do not match.125
The sources also differ on how he was repaid. The National Archives has $108,605.02 coming from the federal government in 1792, calls it all he got, and says Jefferson, writing in 1811, could not recall the case. The Clements Library says the government finally compensated him around 1810. 64 Parishes says Virginia paid a first installment in 1785, that full repayment came from the United States in 1811 and from Virginia in 1819, and that "In the end, he was entirely reimbursed by the United States and Virginia." Wikipedia says Congress cleared his war debts in 1791.1472 The record is a patchwork of payments, and no one source gives the whole of it.
He lived out his years in Mississippi with a daughter, near Pinckneyville. The National Archives, the Clements Library and Wikipedia give his death as 1823, and the Clements Library and Wikipedia say December 17. 64 Parishes says 1824.1423
Did He Invent the Dollar Sign?
Myth: Oliver Pollock invented the $
The popular story says Pollock wrote "ps" for pesos so fast that the letters ran together into a $. Wikipedia's article on the dollar sign calls the "ps" abbreviation the most widely accepted origin of the sign in general, and gives Pollock's example as a letter of 1778, with an image of one dated September 12, 1778, to George Rogers Clark. It also says the sign appears in West Indies business papers of the 1770s, so he was at most one early user.8 One popular article gives April 1, 1778 as the date of his letter, but says plainly that "Nobody knows for certain who invented the dollar sign" and that Pollock was unlikely to be the first to write it.9 Other theories, such as the Pillars of Hercules on Spanish coins, remain in play. The same article lists a theory built on a 1778 Robert Morris design and the old "US monogram" story among those contradicted by the documents.8
The National Archives words it with care: Pollock is "thought to be the first person to write the dollar symbol ($)."1 That is a fair way to put it. The claim rests on the oldest example anyone has found, and no surviving page proves nobody wrote it earlier.
