These are the 24 MacArthur "Geniuses" you should know, including a stem cell biologist, a tap dancer and an economist.

Once a year, the John D. and Catherine T. MacArthur Foundation announces its roster of MacArthur Fellows, a designation frequently referred to as the "Genius Grant." The fellowship bestows upon its recipients a $625,000 prize, along with an accolade that manages to celebrate innovative minds across fields, from science to poetry to painting, and just about everything in between.

This year, the list of MacArthur Fellows ranges from a celebrated writer to an environmental advocate to an inorganic chemist, varying in age from 33 to 72 years old. In total, there are 15 men and nine women represented. The recipients were aware of their award before the 12 a.m. announcement by the MacArthur Foundation this Tuesday. Nonetheless, the winners are celebrating publicly now that the news is out.

"These 24 delightfully diverse MacArthur Fellows are shedding light and making progress on critical issues, pushing the boundaries of their fields, and improving our world in imaginative, unexpected ways," MacArthur President Julia Stasch explains on the MacArthur Foundation website. "Their work, their commitment, and their creativity inspire us all."

The MacArthur Fellowship, founded in 1978, is given out annually to a group of high-achieving individuals in disciplines as diverse as dance, computer science and adaptive design. What was once a $50,000 award has since morphed into a six-figure prize. Past winners include author Cormac McCarthy, photographer Cindy Sherman and astrophysicist Joseph Taylor.
