The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
The second law of thermodynamics can be expressed using different formulations including Carnot's principle, the Clausius statement, and the Kelvin-Planck statement. These laws essentially state that heat naturally flows from hot to cold objects and that it is impossible to create a heat engine with 100% efficiency.
Sadi Carnot and Rudolf Clausius are two scientists who contributed to the development of the laws of thermodynamics. Carnot formulated the principles of heat engines, while Clausius introduced the concept of entropy and the second law of thermodynamics.
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
The three forms of the second law of thermodynamics are: Clausius statement (heat cannot spontaneously flow from a colder body to a hotter body), Kelvin-Planck statement (no engine can be 100% efficient), and the entropy statement (the total entropy of an isolated system can never decrease over time).

An isolated system tend to equilibrium and entropy cannot decrease.

It was said to be first put into words by Rudolph Clausius and William Thomson (Lord Kelvin.) But it was then said it was discovered by the French physicist Sadi Carnot 25 years earlier.
The second law is not so much proven as explained and justified. Like all laws of Science, it is considered a law because no contradictions to the law have ever been found and it is always successful in predicting what we observe in the physical world (within the limitations of what it is supposed to predict). The first to really identify, explain, and apply the second law was Sadi Carnot.

Second Law of Thermodynamics
This statement is based on the second law of thermodynamics, which states that in any energy transformation, some energy is lost as waste heat and cannot be converted back into usable energy. This principle underlies many natural processes and technological systems.
The fact that usable energy is always lost in an energy transfer is due to the second law of thermodynamics. This law states that entropy, or disorder, tends to increase over time in a closed system, leading to the loss of usable energy in the form of heat.
