John Daley (1846 - c. 1890) was a three-time British Classic winning jockey, who most notably won The Derby/Oaks double in 1867.
He received the patronage of owners including Baron Meyer de Rothschild.
[1] He was booked to ride Hermit in the 1867 Derby after the horse had broken a blood vessel in a training gallop and the intended jockey Henry Custance was released to ride The Rake.
Daley brought Hermit for a late run, on the orders of trainer Captain Machell, and won by a neck from Marksman in the final strides.
[1] By early manhood, Daley was struggling to make the weights required.
