The object
Harald Hess co-invented photoactivated localization microscopy, an optical system that localizes fluorescent molecules beyond conventional microscope resolution. PALM gave biologists physical imaging instruments capable of viewing cell structures at the nanoscale, opening a much sharper window on disease-related processes.
01
What Harald did
Co-invented photoactivated localization microscopy with Eric Betzig.
02
Why it matters
NIHF describes PALM as a super-resolution technology that enables nanoscale imaging of biological structures.
03
Living-status check
NIHF records Hess's 2024 induction, a positive dated public award event confirming he was alive in 2024.
