Who is Thomas H. Orde-Lees, motor expert (later storekeeper) from Endurance: Shackleton's Incredible Voyage and what is their importance?

Orde-Lees is the motor expert of the expedition and serves admirably during the early parts of the expedition. He is highly educated and has military experience but is unpopular with most of the other men of the expedition who consider him lazy and condescending. After the destruction of Endurance he is appointed as store keeper and serves with martial zeal in that capacity. He apparently suffers from a dread of starvation and often keeps his personal rations for extended periods. Even so, he is scrupulously honest and is never suspected of sneaking extra portions of the stores over which he has been entrusted.
