Alexander Parkes in 1856.
In 1856, he patented Parkesine (the first thermoplastic), a celluloid based on nitrocellulose treated with a variety of solvents.
The discovery of thermoplastic materials cannot be attributed to a single person, as it is a result of continuous advancements in polymer chemistry. However, some notable early contributors to the development of thermoplastics include Leo Hendrik Baekeland, who invented Bakelite in 1907, and Wallace Carothers, who synthesized nylon in the 1930s. Since then, thermoplastic materials have been further refined and expanded upon by numerous scientists and engineers.

Thermoplastic and thermoset materials both fall under the broad category of Polymers. The biggest difference between a thermoplastic and thermoset is that a thermoplastic can be recycled. Whereas a thermoset irreversibly cure. Thermoplastic: PE, PP, PVC. Thermoset: Bakelite, Epoxy.
thermoplastic
A thermoset is a material that cures or sets into a given shape, generally through the application of heat. A cured, thermoset material will not remelt or otherwise regain the processibility it had before being cured. Curing changes the material forever. A thermoplastic material softens (becomes pliable and plastic) when heated, but it does not cure or set. It can be reheated to be reformed.
LDPE is thermoplastic.

Thermoplastic Rubber (TPR)
It is a transparent thermoplastic.
A thermoplastic material is one that becomes pliable above a certain temperature. They are most commonly used for making molded items. Plastic drinks cups, for example, are made from thermoplastic material.

No. Elastomer = possesses elasticity. As with most rubbers, neoprene is an elastomer. Thermoplastic = can be melted and re-formed. Neoprene is a thermoset material, which means that it will chemically degrade instead of melting.
Celluloid
Wikipedia has an whole article on the topic thermoplastic extrusion. Thermoplastic extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile.
