PETALING JAYA: Google on Wednesday (March 10) paid tribute to Chinese-Malaysian epidemiologist Dr Wu Lien-Teh, who created a surgical face covering widely believed to be the precursor of today's N95 mask.
To celebrate his achievements, Google dedicated its Doodle to Dr Wu on the doctor's 142nd birthday.
