Story summary

Mathematician Cleve Moler died on May 20 at his home in Saint Michaels, Maryland, at age 86.
His daughter Kathryn Moler said Parkinson’s disease caused his death.
In the 1970s he helped develop the FORTRAN libraries EISPACK and LINPACK, which provided standardized prewritten code for complex calculations.
The libraries let engineers and biomedical researchers perform calculations without low-level coding, accelerating work in finance, automobile design and other fields.
