In 1912, he moved to England to become apprentice to Atty Persse in Stockbridge, Hampshire, where he came under the tuition of the stable jockey Steve Donoghue.

His first win was on Hainesby at Bath in 1913, although he had to stowaway in the back of Donoghue's car to get there as the head lad had refused permission for him to leave the yard.

Beary continued to be retained once the Aga Khan moved his horses to be trained by Frank Butters in Newmarket and for a couple of years was very successful.

In 1932, he won the Oaks on Udaipur and was runner up in the 2000 Guineas, Derby and St Leger on Dastur, a colt which proved remarkably successful for him.

Although the odds-on favourite, Sindhi finished fourth, which led Beary to claim that Butters had deliberately put him on a rogue horse.

Beary blamed the incident for the loss of potential rides at Royal Ascot and a negative effect on his bloodstock activities.

Owing to the stigma which had attached to my name in consequence of my treatment by Mr Butters, I found it extremely difficult to obtain purchasers or good prices for my stock and this caused a serious loss.

In the 1940s he was retained by Sir Malcolm McAlpine and he was in his fifties when he had his most prolific season - 81 winners in 1949, including a second St Leger on Ridge Wood for Noel Murless.

In his first season, 1951, he won the 2000 Guineas with Ki Ming, a horse that had been trained by his brother John, until his licence was withdrawn for doping.
