Heroes whom we do not recognize - 2

Another inventor, Carrier invented something that is used every day in most countries - air conditioning. An engineer, Carter invented the first modern air conditioning system that included the four crucial controls all air conditioning systems must have:

1. control temperature; 2. control humidity; 3. control air circulation and ventilation; 4. cleanse the air.

Without these 4 elements, air conditioning was downright dangerous to use over time. In 1911, Carrier presented his initial schematics, what became known as the 'Magna Carta of Psychometrics', making it possible, for the first time ever, to design air conditioning systems that fit whatever requirements needed. There is no doubt that this invention not only increased quality of life around the world, but also saved many from dangerous temperatures.

Rick Rescorla wasn't a scientist or a leader. There was nothing special about his blood. There was only something special about his courage. In the morning of 9/11, Rescorla heard the explosion at the tower, while he himself was in the Morgan Stanley office located in the second tower.

While the P.A system was urging people to stay where they are, rick, a retired US officer and a Vietnam war veteran, grabbed his bullhorn and walkie-talkie and evacuated thousands of people from the tower, even after the second plane hit. When he was told to evacuate himself, he refused saying there were more people to evacuate, he was last seen going up to the 10th floor when the building collapsed, and his remains were never found. Rick Rescorla deserves to be remembered as a hero.

Maurice Ralph Hilleman

First on our list is the man who saved more lives than ANY other medical scientist in the 20th century. How did he do it? Hilleman, who unfortunately passed away a few years ago, was an American microbiologist who developed over 36 vaccines, many more than any other scientist. Among those vaccines: Hepatitis A, Hepatitis B, Chickenpox, Measles, Mumps, Meningits, pneumonia and types of influenza bacteria.
