His crimes stretched across two countries and several decades, targeting vulnerable young men who crossed his path at different points in his life. The killings in Germany came first, followed years later by further murders in the United States, a pattern that underscores how long he operated before facing a final reckoning. A confession left in his jail cell acknowledged five victims — a closing act that arrived only after the courts had already reached their own conclusions.

His place in history rests largely on a single act: the 1924 killing of Jacob Israel de Haan, widely considered the first political assassination carried out by a Jewish underground organization in Mandatory Palestine. As a Haganah commander who went on to found and lead the Irgun, Tehomi helped shape the early architecture of Zionist paramilitary action during the British Mandate period. His later confession — offered without remorse — framed the killing not as a crime but as a necessary measure to protect the Zionist project from a man he believed would undermine it.

Yale's inclusion here rests on his tenure as President of the East India Company's Madras settlement, where he was removed from office on charges of corruption and self-dealing — a career shaped as much by personal enrichment as by colonial administration. The fortune he brought back to Britain, built largely on the diamond trade, bore the marks of a system in which company officials routinely exploited their positions at the expense of local populations. That wealth was later laundered into philanthropy, most famously the donation that gave Yale University its name.
