Seems reasonable to give some credit here - it came close. The key difference i guess was to add the visible vapor. Actually making the product successful is also a big step. To be fair to the 1963 patent, the
batteries of those days would no way have been up to job, not without being huge anyway.
The Gilbert design was not unlike the BT inhaler product (forget its name) that was around for while some years ago. Heat the
tobacco to release it's vapors; though Gilbert does talk about additional chemicals (solvents?) and 'moist air'.
edit: well, not that similar actually, the 'Premier' (?) heated tobacco while Gilberts designed used a solution of extract or plain nicotine.
The e-cig we know today was invented in 2004. Though even that used a different mechanism (a piezo-electric tranducer to vibrate liquid into a mist, like cold steam humidifiers) to the simple heater coil plus wicking that actually achieved success. There were a few important players in China who took the interest (mainly from the US) and made effective and affordable models. So one might also ask who created the first heater coil type atomiser? (Maybe it was Ruyan; maybe another company).

"Gilbert design AN electronic cigarette, not THE electronic cigarette.
While Herbert Gilbert’s and Hon Lik’s devices share the same name, look similar on the outside and both use a battery, they actually function very differently and produce different results. Gilbert’s device is designed to heat air, which is then sucked through a flavored filter and produces no visible vapor. Lik’s design heats a liquid until it becomes a visible, inhaled vapor – which is how all of our e-cigarettes function today. Therefore, Lik is considered by most to be the inventor of the modern e-cigarette.
Gilbert was definitely a man ahead of his time and on the right track, but he is not the inventor of modern e-cigarettes anymore than Sony is considered the inventor of the iPod just because they came up with the idea of a compact personal music player first. While both inventions are small, rectangular, deliver music through a headset and run on
batteries, the Walkman and the iPod function very differently – just as Gilbert’s design functioned very differently from Lik’s – so no one considers Sony the inventor of the iPod.
Hon Lik deserves the credit he gets for being the inventor of the e-cigarette design we use today."
