The name Toll springs from the small village Tollstad, south of Alvestra in the province of Östergötland, Sweden.
Toll played the main role in the construction projects while Ivar Kreuger handled the business contacts and marketing of the company.
To start with in the match-industry to save the Kreuger family match factories around Kalmar that was facing financial problems in 1912 and later in other industries.
Paul and Ivar, however kept a close contact over the years as Ivar insisted on keeping Paul as a member of the board for Kreuger & Toll AB, handling the Kreugers construction business within the subsidiary real estate company Hufvudstaden AB.
Henrik Kreüger, Ivars Kreuger's cousin, was working as a consultant and chief engineer for the company from the start in 1908 and played a major role in the construction business success.
To what extent Ivar was involved in the construction business beyond 1917, when the Swedish Match had been founded and the Russian subsidiary company was closed down, is not clear but he certainly had business contacts that the Kreuger & Toll Construction AB could benefit from, and Ivar and Paul often met in their free time.
