Corbett enjoyed a successful career in the City going back almost two decades, also working previously for Merrill Lynch.
Just 41-years old, he died of asthma-related heart failure immediately following the successful completion of a half-marathon in Essex on Sunday. Although he was attended to by medics at the scene, he was pronounced dead after being taken to a local hospital.
Trent Hagland, Head of Credit Trading at MUSI, said: 'I had the honour of working with Andrew for many years. Not only was he a fantastic professional but also a very good friend to all those who worked with him. His attitude, loyalty and integrity were of a standard rarely seen in this industry. Everyone associated with Andrew will miss him dearly and never forget him'.
Colleagues and friends are now raising funds in his memory for charity and, in just 3 days, over £44,000 ($71,100) has already been raised.
