context_page_description: Andreas Collstrop was a Danish businessman. He inherited the timber company R. Collstrop in 1988 and opened Denmark's first wood preservation facility at Køge in 1889.
context_section_description: Collstrop was licensed as a merchant in 1871. His father's death in 1877 left him as the sole over of the family business. After a few years he transformed the company from a timber retailer to a commodity broker and wholesale business in a scale that made it one of the largest and most reputable in the industry. He opened a tic mill at Køge in 1888 which was followed by Denmark's first wood preservation facility, Imprægneringsanstalten , the following year. The tic mill was later moved to Danzig. A second wood preservation facility opened at  Horsens 1900.
  His activities in Danzig made him move into forestry in Germany and Russia. In the 1890s, together with Julius Rutgers he established a timber preservation in Russia which operated a total of eight factories in the southeastern part of the country. This part of his timber empire was lost at the outbreak of the Russian Revolution.
  Part of the company was in around 1910 sold to Schmidt & Bloch and the remainder was 1914 converted into a limited company (aktieselskab) with Edvard Bülow as managing director. Collstrop remained chairman of the board until his death.
  Collstrop was also a co-founder of Kjøbenhavns Flydedok & Skibsværft. He served in the board for many years. He was from 1914 also a board member of Den Danske Landmandsbank. He was therefore drawn into the Alberti Scandal in 1922 and ended up having to pay approximately DKK 1 million in compensation to the bank,
