Seriality

The man who kept a ledger of coincidence

Seriality · 1919 · Vienna

Serie

DocumentA book of about a hundred everyday recurrences. Not a miracle catalogue.

He treated coincidence as something one could collect.

Paul Kammerer walked Vienna and wrote down repeats: a number, a name, a tram, a person twice in an afternoon. He classified them. In 1919 he published the collection and called the regularity a law of seriality. The cases are often small. That is the point. He was not hunting wonders. He was hunting series.

Sourced

The German book is the primary. Later English readers often meet him through Arthur Koestler. Koestler is a retelling, and a defense. Start with 1919 if you can.

Miss

His later scientific disgrace in another field is sometimes used to close this book without reading it. Read the ledger. Then read the controversy. They are not the same page.

A pattern needs a denominator. A ledger is already a selection.
