Quick answers
What did Charles Ponzi claim to be doing?
He told investors that profits would come from buying and redeeming International Reply Coupons across borders. Investigators in 1920 showed that coupon issuance could not support the money he was taking.
When did the scheme collapse?
Public unraveling came in July-August 1920 as the Boston Post published its investigation and investors sought redemptions. Ponzi surrendered to authorities in August 1920.
What was he convicted of?
He pleaded guilty to federal mail fraud in 1920. Massachusetts later convicted him of larceny after a 1922 mistrial and a 1925 guilty verdict. He served federal then state time.
How much money was involved?
Contemporary estimates commonly cite about $15-20 million in 1920 dollars of liabilities or take, with tens of thousands of note-holders. The figure is not comparable, unadjusted, to late-twentieth-century cases.
Did the Boston Post really break the case?
The Post's July-August 1920 reporting, using Barron and postal facts, is the investigation the Pulitzer board later honored. State and federal officers were already looking; the newspaper made the arithmetic public.
Was this the first such fraud?
No. Earlier promoters had paid old investors with new money. The 1920 Boston collapse is the namesake event in English, not the first instance in history.
The 1920 file is smaller than a modern DOJ task force. The names below are the ones the Post and the dockets keep.
Roles are taken from contemporary reporting, the federal plea, and the Massachusetts larceny record.
People
Clarence W. Barron
Publisher; public arithmetic
Head of the financial publishing house that became Barron's. His 1920 analysis of coupon volume gave the Post a market-size fact it could print.
Richard Grozier
Boston Post publisher
Publisher who backed the 1920 investigation. The paper received the 1921 Pulitzer Prize for public service for the Ponzi campaign.
Edwin C. Grozier
Boston Post (context)
Longtime Post publisher; the paper's investigative culture in 1920 sat in a family enterprise that treated the coupon story as a civic campaign.
Joseph Pelletier
Massachusetts prosecutor context
Boston district attorney during the unraveling; state larceny work proceeded alongside the federal mail-fraud case (offices and successors completed the 1925 conviction).
Rose Ponzi (Gnecco)
Spouse; contemporary witness
Appears in 1920 press accounts of the household and the surrender week. Not a criminal defendant in the mail-fraud plea.
Later textbook names (SEC staff, modern judges) use 'Ponzi' as a doctrine. They are not 1920 Boston actors.
