I constantly forget which is Camel case and which is Pascal case. So I thought that maybe a little history will help. Where do the names of these conventions come from? Is there some history behind their names?

Camel case and Pascal case are similar. Both demand variables made from compound words and have the first letter of each appended word written with an uppercase letter. The difference is that Pascal case requires the first letter to be uppercase as well, while camel case does not.
When multiple words are used to form a variable, camel case joins those words together, without any white space, and delineates the start of each new word with a capital letter. In contrast, snake case uses an underscore between words to create separation.
Meaning of camel case in English. the use of a capital letter to begin the second word in a compound name or phrase, when it is not separated from the first word by a space: Examples of camel case include "iPod" and "GaGa".
Results indicate that camel casing leads to higher accuracy among all subjects regardless of training, and those trained in camel casing are able to recognize identifiers in the camel case style faster than identifiers in the underscore style.
To remember camel case you have to think about the shape of the capital letters. They are like the humps of a camel as you can see in this image.
Pascal Casing - capitalizes each word:
ThisShouldBePascalCase
Camel Casing - is similiar to pascal case but the first word is not capitalized:
thisShouldBeCamelCase

UPDATE: Change the camel case image after reading the comments.

Pascal is a persons name... a persons name always starts capitalized, whereas 'camel' is just a noun and thus, unless the start of a sentence, is always lowercased.
