Ponzi's initial investors consisted of working-class immigrants like himself. Gradually, news traveled upwards, and many well-to-do Boston Brahmins also invested in his scheme. In its heyday, nearly 75% of Boston's police force had invested in the scheme. Ponzi's investors even included those closest to him, like his chauffeur John Collins and his own brother-in-law. Ponzi was indiscriminate about whom he allowed to invest, from young newspaper boys investing a few dollars to high-net-worth individuals, like a banker from Lawrence, Kansas, who invested $10,000. Summarily, he was willing to take any cent from any investor.
