Indoor plumbing, the transistor (without which there would be no digital electronics), plastics.  I would agree with the "wheel" answer, except that it came around long before the engineering profession and was probably invented by some caveman.  You could also include scientific principles that have been discovered and subsequently led to great engineering feats.  For instance, Maxwell's Laws of Electromagnetism (the principle on which all wireless devices work), Bernoulli's Principle (the basis for airplane wing design) and so on.

i think the most useful invention to mankind would be electricity. without electricy, none of our current "conveniences" would be useful. without electricity, we would have no lights, no heat, no indoor hot water, no refrigeraation for food...electricity started it all and I feel it was and is the most useful to mankind.

Hands down--no debate--the greatest invention, the invention that has altered the course of humanity more than any other--is the printing press.  How could ANY of the later advancements have been developed without the power to reproduce the printed word?

I think the scientists who made the greatest contribution of all time was Alexander Gram Bell even though he was not really scientists and more like a inventor. His invention the telephone is what now makes the world go round. The telephone lead to the internet, and being able to send mass amounts of information.

I don't think anything has been invented that can't be hacked into. If you come up with that you will become a millionaire! There will always be thefts ... or someone trying.

"celver" or CLEVER???\n I think anybody on earth have the ability to be Clever as long as they open their mind to new things that are happening everyday. \n I also think there are more American inventors than English investors, but then who cares? We all learn from each of them!
