The "Famous Engineers" Series

Engineer
Proves Mussolini Wrong |
|
|
|
Sometimes it takes a challenge to make a person perform at his best. And this challenge was a big one. |
|
|
|
It took until World War II for
this Oregon State University engineering graduate to really make a mark. It was at this time that he became a Chief Engineer for Henry Kaiser’s newly formed ship building operation and later general manager of Oregon Ship, one of Kaiser’s three shipyards on the Willamette River in the Pacific Northwest. |
|
|
|
Prior to this time, the Northwest had not been known for shipbuilding activities, but the newly appointed general manager and his boastful boss were about to change all of that. His shipyard was located near St. John’s Bridge, and he built the Liberty Ships – the 10,500-ton cargo ships that carried supplies, equipment and troops to the front lines of battle. |
|
|
|
America sorely needed a fast supply of the Liberty Ships. Without the supplies, equipment, and manpower delivered by the Liberty Ships, certainly the Axis would have a real advantage over the Allied forces. Italian dictator Benito Mussolini unknowingly provided the stimulus that moved this engineer to fast action. |

|
These late summer days in August and
September can sometimes be brutally hot. A last blast of heat before the cool of autumn
takes over.
They call it the Dog Days of Summer. And it can be miserable. |
|
|
|
Back before the days of HVAC … before the days of refrigerated air … in
the early twentieth century, theater patrons in Chicago were treated to
cool air as they enjoyed the show. It may have been The Last of the Red
Hot Mamas on the vaudeville stage, but in the theater, Mama (and for that
matter, Daddy too) were basking in the cool air. |
|
|
|
How did the Chicago theaters get cool air on a hot night before electric
air conditioning? |
