James Ogilvy, who has died aged 89, was a popular City stockbroker and asset manager with royal connections; as a partner of Rowe & Pitman – known in the 1970s as “the Queen’s stockbroker”, but also a powerhouse of institutional equity sales – Ogilvy specialised in private-client dealings and was instrumental in creating a range of services for smaller investors under the subsidiary brand of Rowan Investment Management.
