Sir Denis John Wolko Browne KCVO (2 April 1892 – 9 January 1967) was the first British surgeon to devote his practice entirely to the care of children.

A native of Australia, he served in the Royal Australian Army Medical Corps in World War I before moving to England and joining the staff of the Hospital for Sick Children at Great Ormond Street.

He devised his own approach to the repair of hypospadias and worked on improvements to the management of other genitourinary, gastrointestinal, orthopaedic and cardiovascular problems.

[2] A tall, athletic youngster, Browne had been given the middle name Wolko, which was an Aboriginal word for "big man".

[8] He paid special attention to the surgical problems of newborns, and he introduced new thoughts on the development and management of conditions such as club foot and hypospadias.

He also realised that one of the common steps in such repairs – the transfer of skin from the foreskin to the ventral surface of the penis – was unnecessary.

Because there were only thought to be 50–60 paediatric surgeons in the world at that time, BAPS quickly developed an international membership.

[2] His son is the libel barrister Desmond Browne QC, a former Chairman of the Bar of England and Wales.

[16][17] In his room at Great Ormond Street, he painted a line at the level of a tennis net so that he could practise his shots.

He created a round tennis racquet that he felt was superior to the traditional oval, and he was known to modify his own guns.

When he was at Great Ormond Street, Browne created a universal golf club with an adjustable angle of lift.

Four years later, he was made Knight Commander of the Royal Victorian Order (KCVO) and Chevalier of the Legion of Honour.
