Al Capone was America's most notorious gangster during the 1920s Prohibition era. He was born in Brooklyn in 1899 and rose to power bootlegging illegal alcohol and running illegal gambling operations in Chicago. At the height of his criminal empire, Capone was making over $100,000 per week and his entire operation was worth over $62 million. Capone ordered the infamous 1929 Saint Valentine's Day Massacre that eliminated his main rival. He was ultimately arrested in 1931 and convicted of tax evasion for failing to pay income taxes on his illegal earnings, serving prison time before dying of cardiac arrest in 1947.
