British jump racing horse trainer; the most successful trainer of jumpers ever to have been based in Scotland. Three times, twice with Wyndburgh and once with Moidore's Token, Oliver was second in the Grand National. He also sent out Drumikill to finish runner-up in the Champion Hurdle at Cheltenham, but though he never won any of jumping's three major prizes, few other top races eluded him and he won the Scottish Grand National on five occasions.
