Yes, that's right. (The very earliest version was based on work 13 years ago by Paul Le Roux, but it's undergone enormous work since then by some person or group.)
TrueCrypt is a popular, carefully designed, well written, well maintained,
highly stable and non-trivial application, but its authors are completely
unknown. The open source world does have some quiet humble people, but it
seems surprising that the authors want to remain totally anonymous
for developing a legitimate and well-respected product.
Interesting. About anonymity, there is always the case where you don't want people knocking at your door to ask for backdoors, hidden vulnerabilities or any other requests about the software that you don't want to deal with.

People continually discover this and are shocked to learn that the authors are anonymous. This has been a known fact since at least 2005. The authors of TC are anonymous and have been for a very, very long time.
What do they mean by this? Do we literally don't know who created Truecrypt?
