I want to know the answer to the following question:
At what company were Meucci's prototypes supposedly lost?
All the background I'm provided with is that "Meucci's evidence in this case was disputed due to a lack of material evidence for his inventions as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901.". Is that enough to answer the question?
Answer: yes
