Andrija was born 1 September 1888 in Brodski Drenovac, in modern Požega-Slavonia County. He enrolled at the Medical School in Vienna in 1906, which was at the time the most important medical center in the world. On 23 December 1911, he was awarded the title of Doctor of Universal Medicine.
In 1919, he attended the Congress of Inter-Allied Countries for Social Hygiene in Paris giving a lecture on children's health. It showed at that time that he had a clear concept of organizing the public health service. Andrija Štampar is universally known as "the man of action".
At the young age of 31 he became principal of the former Yugoslav Health Service in Belgrade (Beograd). Thanks to Štampar's endeavours, a special Institute of Social Medicine was founded affiliated with the University of Zagreb School of Medicine.
From 1931 to 1933, Štampar was permanently employed as the expert of the League of Nation's Health Organization. The Health Organization sent him as an advisor to help the Chinese health administration in the control of the mass infectious diseases that cropped up after devastating floods in 1931.
Dr. Štampar has come to China to help our Government in its work on reconstruction based on the plan of technical cooperation with the League of Nations. He went round several provinces, from Kansu and Shanghai in the West to Kwangtung and Kwangsi in the South, and made a valuable contribution to the reconstruction of our villages, especially in the field of rural health protection services. On his departure we wish to give this to him as a remembrance of his work in China, hoping he will come to visit us again.
