The original EZ curl bar was invented by Lewis Dymeck in 1950
Even then, it was recognized that curling with the straight bar was stressful on the biceps tendon and wrists for many lifters
Dymeck filed the patent, and the Jackson Barbell company started making the bars

Ive recommended the EZ curl bar over the straight bar for some years
You want maximal muscle stress, minimal joint stress of any kind
If you want to curl heavy, use the EZ bar

Dymeck thought the same, the following is from the patent he filed in 1950 describing his invention:
As therefore proposed, the straight bar bell device is one that is used for the standard exercises to effect the development of the arms and biceps. In these exercises, the instructions are always the same and recite that the exercise must be done with strength of arms alone...
while keeping the elbows close to the user’s sides, without swinging the body.
However, very few persons can do such exercises correctly, since it is not natural or comfortable to do such exercise with a straight bar bell.

It has been found that by providing the bar of the bar bell with a pair of tortuous portions in proper spaced relation intermediate its ends so as to form hand grips, a bar bell is produced which overcomes the disadvantages of the conventional straight bar bell.
Accordingly, an object of this invention is to provide a bar bell for exercising purposes which will permit the exercises to be done correctly without body movement or strain.
