David Lim (born 1964) is a Singaporean mountaineer and motivational speaker who led the first Singapore Mount Everest Expedition in 1998. Between 1994 and 1998, he led and organised a team from the flat tropical island nation to the top of Everest. Sustaining an injury on the summit push, he did not make the summit himself though two other team members succeeded in making the top on May 25, 1998. A week after his return, and not related to the climb, he was stricken with Guillain-Barré syndrome, a rare nerve disorder where the immune system attacks the peripheral nerves. Paralysed from eyes down, he spent six months in hospitals, and emerged partially disabled in both legs.
