About

Irwin Union is an infrequently published letter that shares long form writing on financial and market history.

Each issue is likely to be different, but philosophically, they will all be oriented towards through cycle analysis, and interested in relatively long stretches of corporate or market history.

Irrespective of subject matter, issues of Irwin Union are unified in their focus on archival sources. The core of the letter is an emphasis on original research and the sourcing of primary documents for as far back in time as is practicable.

The letter is named for the Irwin Union Bank & Trust Company of Columbus, Indiana. The Irwin Union Bank & Trust building, designed by Eero Saarinen, was one of the first modernist banks in America.
