If we use your criteria of "......some of the great designers for engineering skill and knowledge...........", then this list is somewhat flawed. The list, as it stands now, looks to me as if it was assembled from image, as opposed to actual engineering know-how.
Either that, or you will have to re-define your criteria. In that case, it might could stand.
