Sir Roger Antony Hornby (5 February 1904 – 20 December 1987), was senior partner at the stockbrokers Cazenove.

Roger Antony Hornby was born on 5 February 1904, the second son of St John Hornby and his wife Cicely Rachel Emily Barclay.

According to Anthony Hilton, he rebuilt Cazenove after the war, by subtly acknowledging his company's place in the City hierarchy.

And up until the 1970s, no member of staff could visit a merchant bank without wearing a bowler hat.

Hornby was also president of Savoy Hotel Ltd.[1] Hornby married Lady Veronica Brenda Hamilton-Temple-Blackwood, daughter of Frederick Hamilton-Temple-Blackwood, 3rd Marquess of Dufferin and Ava, on 17 December 1931.
