Moritz Erhardt, Bank of America intern who died

The widespread culture of long working hours and all-nighters for banking interns has been criticized after the death of a 21-year-old intern last week, with recruiters and human resources groups calling for changes to guidelines and working practices.

Moritz Erhardt, collapsed at his London home in Bethnal Green on Thursday, after reportedly working until 6 a.m. for three days in a row at Bank of America Merrill Lynch's (BofA) investment banking division. The cause of death is unknown and some newspapers reported that he suffered from epilepsy.
