If you don't know of Raymond Loewy then he is one of the two or three individuals from the 20th century in America who have made design the impactful reality in products - from maximizing on revenue to the consumer feeling the "need" to "must have" a particular brand.
Wired magazine online profiled Raymond Loewy in November here. Also, I visited an informative exhibition on Raymond Loewy chronicling his design through the decades including family and commercial videos in Bozeman, Montana called "Raymond Loewy:Designs for a Consumer Culture". See details here.
For me there is no getting away from the fact that Raymond Loewy brought together the initial principles of Industrial Design, perhaps not all of them yet the most important ones, including that it begins and ends with the consumer, in delighting the consumer through design and the experience that design imparts for the consumer of the product.See a photo gallery of Raymond Loewy's designs here on Wired online.
