In the 1950s, Wenner-Gren also got involved in the early computer business. For a railroad project connecting
California with
Alaska, he got in touch with
Glenn Hagen, previously an engineer with
Northrop Aircraft, who had founded Logistics Research in
Redondo Beach outside Los Angeles, developing computers based on magnetic
drum memory. In November 1952, Wenner-Gren helped the company to incorporate. He soon controlled the company and renamed it ALWAC (the Axel L. Wenner-Gren Automatic Computer). ALWAC I was used in 1953, ALWAC II and ALWAC III in 1954,
ALWAC III-E in 1955. In 1956 and 1957, the model ALWAC III-E was considered a competitor to the
IBM 650, having fewer parts and good economy, but no more than 30 units seem to have been delivered. Soon after this, magnetic drum machines were made obsolete by the introduction of the
magnetic core memory. By 1956 the number of employees tripled to over 300 and the company was relocated to an industrial park in
Hawthorne, California. The appearance of the
transistor in the electronics industry in 1957 was a financial shock for all vacuum tube computer makers and by 1958 ALWAC in Hawthorne closed and its employees, with the help of Wenner-Gren himself, were successfully hired by
Litton Industries and
Autonetics and several smaller electronics companies. The follow-up ALWAC 800 was a failed design that never went beyond prototype, using not only core memory but also
magnetic logic (a combination of semiconductor diodes and magnetic cores, cf.
Hewitt Crane), and presold contracts nearly ruined the company. Development was transferred to Sweden in 1958. The next model, named Wegematic 1000, a slight upgrade of the III-E, was shipped in 1960. Only a dozen were delivered and half of them were give-aways to universities, including one unit for the
Weizmann Institute in Israel. In exchange, Wenner-Gren received several honorary titles. Among Wenner-Gren's other interests were
monorail train systems. His company,
ALWEG, built the original
Disneyland Monorail System in 1959 and the
Seattle Center Monorail in 1962. Wenner-Gren continued his fascination with speculative railway projects, as he collaborated with Canadian
W.A.C. Bennett to build a railway north from
Prince George into the untapped
Peace River,
Rocky Mountain Trench and eventually
Alaska. Parts of the railway were built by the
Pacific Great Eastern Railway after Wenner-Gren's death, including the needless
Fort Nelson branch, yet the meeting produced outcomes lasting to this day. The interest in the north spurred a spate of mega-industrial projects in the region: the
Bennett Dam flooding vast valleys, gas pipelines and plants at Taylor, coal mines and pulp mills. ==Personal life==
