Clown doctor Peter Spitzer has lost his battle with cancer.
Australia's best-known clown doctor and Bowral general practitioner was farewelled on Saturday.
Dr Spitzer was fondly known as Dr Fruit-Loop and was the co-founder and medical director of The Humour Foundation.
The beloved doctor became Australia's first "clown doctor" in 1997 after creating the foundation.
The charity is dedicated to promoting the health benefits of humour.
Dr Spitzer was often found wandering hospital corridors around the country dressed in a funny hat and carrying a big bag of magic tricks, determined to make sick children smile.
Since establishing The Humour Foundation, Dr Spitzer and clown doctors around Australia have brought smiles and laughter to more than 150,000 sick children and their families.
Laughter and smiles were also brought to the elderly, with Dr Spitzer's establishment of the Elder Clowns program, which helps those living with dementia.
Most importantly, the clown doctor educated everyone about the importance of humour and laughter to health and in life.
He was a true master of the motto, "laughter is the best medicine."
If you would like to send any messages of condolence or celebration of Dr Spitzer's life, a memorial page has been set up.
