Smith's piece was visceral and highly critical of the banking giant, but he's not the only financial executive to use the printed press to announce a resignation.
In 2008, Andrew Lahde took to the pages of the Financial Times to announce the dissolution of his company Lahde Capital Management. In the process, he tore through the likes of Bear Stearns, Lehman Brothers and AIG, with less than flattering words for their fellow staff.

Long before the days of social media and YouTube, a public resignation was a trickier act to pull off -- but not if you're one of the UK's leading politicians.
In his resignation speech to parliament, then deputy prime minister, Geoffrey Howe, ripped into his boss, Prime Minister Margaret Thatcher, chastising her for policies on Europe and an inhibiting style of government.
Conservative party colleagues looked on stunned while Thatcher barely turned to acknowledge her long-time colleague.
Across the aisle, opposition Labour politicians howled with laughter, whooping at the misfortune of the PM whose politics they despised so much.
Only a few days later, Thatcher was ousted by her party and left Downing Street in tears.
