From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
Huffman coding          A {data compression} technique which varies the       length of the encoded symbol in proportion to its information       content, that is the more often a symbol or token is used, the       shorter the binary string used to represent it in the       compressed stream.   Huffman codes can be properly decoded       because they obey the prefix property, which means that no       code can be a prefix of another code, and so the complete set       of codes can be represented as a binary tree, known as a       Huffman tree.   Huffman coding was first described in a seminal       paper by D.A. Huffman in 1952.          (1994-12-23)
