Now I know who is the human shown in photo #2:
[13 Sep 1916 – 23 Nov 1990]
I still don't know what are the dogs' first names, but I believe that their family name is also Dahl. *
* *I also have known, since about 5 minutes ago, that Roald Dahl [13 Sep 1916 – 23 Nov 1990] was a British writer, a popular author of ingenious, irreverent children's books such as The Gremlins (1943), James and the Giant Peach (1961), Charlie and the Chocolate Factory
(1964), *Fantastic Mr. Fox (1970), The Enormous Crocodile (1978), Matilda (1988).
* * Dahl also wrote books for adults, such as Someone like You (1953) and Kiss, Kiss (1959), and scripts for movies, including You Only Live Twice (1967) and Chitty Chitty Bang Bang (1968). Other movies were made from some of his books.
* * I like better this picture of him (but I don't know the names of the giraffe, the pelican, and others in the same picture):
