Pause for a moment to reflect on Walter Porstmann’s legacy right here. He rests in Berlin’s Lankwitz Cemetery. Though his grave is no longer an honorary one, his contributions remain monumental.
Walter Porstmann was born in Geyersdorf in 1886. He became a pivotal figure in German standardization. Specifically, he established the German paper sizing standards.
Porstmann’s academic journey began at the Universities of Erlangen, Kiel, and Leipzig. He excelled in mathematics, physics, and applied mathematics. From 1912 to 1914, he served as an assistant to Nobel laureate Wilhelm Ostwald. Ostwald influenced Porstmann’s thinking on standardization.
In 1917, Porstmann published “Normenlehre.” This book caught the attention of Waldemar Hellmich. Hellmich was the managing director of the German Institute for Standardization. In 1918, Porstmann earned his doctorate. His dissertation focused on the structure and unification of measurement systems.
Joining the German Institute for Standardization in 1920, Porstmann connected the “Weltformat” with metric measurements. The DIN A0 format was defined to have an area of one square meter. He also introduced the B series. It provides slightly larger sizes for envelopes.
The DIN 476 standard “Paper Sizes” was published in 1922. Wunsiedel was the first district office to switch its paper formats to the A series. In 1923, Porstmann became the managing director of Fabriknorm GmbH. This company manufactured related items from card index boxes to files.
Walter Porstmann also advocated for lowercase writing in Germany. He believed it would improve efficiency. He even designed a new phonetic alphabet.
In 1944, Porstmann received the Ring of Honor from the German Institute for Standardization. He authored 16 books. He also penned hundreds of articles, reports, and book reviews.
The international standard ISO 216 emerged from DIN 476 in 1975. The A4 format became globally dominant. Only the USA, Canada, and some Central and South American countries still use inch-based paper sizes.
Think about it. Every A4 sheet connects you to Walter Porstmann. His quest for order shaped our world. His innovative mind rests here. He left a lasting impact on global communication.
