Walter Zapp (born Sept 4th 1905 in Riga, died July 17th 2003 in Binningen near Basel, Switzerland) was one of the pioneers of photography. He was the inventor and constructor of the legendary Minox subminiature camera. In 1934 he developed this smallest industrially produced film camera. In Zapp's lifetime nearly one million of these cameras were sold. In 2001 he got the honorary doctorate of the Latvian Academy of Sciences and was decorated with the Order of the Cross of Terra Mariana for his special services to the Republic of Estonia. Eesti Post has issued a Europa postage stamp in 1994 to commemorate Walter Zapp and his patented invention (Estonian patent No. 2628), the Minox subminiature camera.
