The founder of Danbury-based MannKind Corporation has died.  Alfred Mann passed away yesterday at the age of 90.  The LA Times reports that he died in Las Vegas, where the entrepreneur had spent the majority of his time over the past several years.  His cause of death was not reported. 

MannKind announced this month that the founder of the company resigned as Executive Chairman and from the Board of Directors.  MannKind CEO Matthew Pfeffer said that Al founded the company in order to bring his unique flair for medical innovation to the biopharmaceutical space. 

Mann served in the Army Air Corps during World War II, though he didn't see combat duty, and helped improve missle guidance systems technology.
