How do thermos work?
A thermos works with principle of Physics that vacuum is a pure insulator of heat. Thermos is made of two containers separated by a vacuum space which acts as an insulator of heat. Also the surface of thermos will be glassy which in turn helps in reduction of heat loss.
Is a thermos an insulator?

Who create a thermos?
This is from wikipedia:The vacuum flask was invented by Scottish physicist and chemist Sir James Dewar in 1892 and is sometimes referred to as a Dewar flask after its inventor. The first vacuum flasks for commercial use were made in 1904 when a German company, Thermos GmbH, was formed. Thermos, their trademark for their flasks, remains a registered trademark in some countries but was declared a genericized trademark in the U.S. in 1963 as it is colloquially synonymous with vacuum flasks in general.

How does the thermos maintain heat?
A real one is a vacuum flask (or better: two flasks with a vacuum between them) - and so the only heat loss is via radiation (except at the cap). But most today are simply foam insulation.
