Ahlberg & Ohlssons Instrument AB [A&O]
- Ann-Marie Nilsson
Swedish brass instrument manufacturer, active in Stockholm from 1850 to 1959. The firm was established by Olof Ahlberg (b Landskrona, 13 Nov 1825; d Stockholm, 29 Sept 1854) and Lars Ohlsson (b Landskrona, 7 Nov 1825; d Stockholm, 1893), journeymen who trained from about 1840 to 1850 with Jacob Valentin WAHL in Landskrona. A&O had 20 employees in 1866. Within a few decades the firm drove minor makers and dealers from the Swedish market or bought them up (e.g. the Stockholm dealer Bengt Dahlgren, acquired in 1894). After the death of Lars Ohlsson, the firm was run by his son Alexis Ohlsson (1859–1932). From 1932 Harry Ohlsson, the son of Alexis, was a member of the board. The firm operated from 1904 as a limited company (aktiebolag, or AB). A&O exhibited in London (1851), Moscow (1863, 1872), Stockholm (...
