An abecedarium (or abecedary) is an inscription consisting of the letters of an alphabet, almost always listed in order. Typically, abecedaria (or abecedaries) are practice exercises.

Some abecedaria include obsolete letters which are not otherwise attested in inscriptions. For example, abecedaria in the Etruscan alphabet from Marsiliana (the Tuscana town) include the letters B, D, and O, which indicate sounds not present in the Etruscan language and are therefore not found in Etruscan inscriptions. Others, such as those known from Safaitic inscriptions, list the letters of the alphabet in different orders, suggesting that the script was casually rather than formally learned.

Some abecedaria found in the Athenian Agora appear to be deliberately incomplete, consisting of only the first three to six letters of the Greek alphabet, and these may have had a magical or ritual significance. A deliberately incomplete abecedarium found at Hymettos in Attica may have been a votive offering.

Gilles Deleuze (French pronunciation: [ʒil dəløz]), (18 January 1925 – 4 November 1995) was a French philosopher who, from the early 1960s until his death, wrote influentially on philosophy, literature, film, and fine art. His most popular works were the two volumes of Capitalism and Schizophrenia: Anti-Oedipus (1972) and A Thousand Plateaus (1980), both co-written with Félix Guattari. His metaphysical treatise Difference and Repetition (1968) is considered by some scholars to be his magnum opus.

Deleuze was born into a middle-class family in Paris and lived there for most of his life. His initial schooling was undertaken during World War II, during which time he attended the Lycée Carnot. He also spent a year in khâgne at the Lycée Henri IV. During the Nazi occupation of France, Deleuze's older brother, Georges, was arrested for his participation in the French Resistance, and died while in transit to a concentration camp. In 1944, Deleuze went to study at the Sorbonne. His teachers there included several noted specialists in the history of philosophy, such as Georges Canguilhem, Jean Hyppolite, Ferdinand Alquié, and Maurice de Gandillac, and Deleuze's lifelong interest in the canonical figures of modern philosophy owed much to these teachers. Nonetheless, Deleuze also found the work of non-academic thinkers such as Jean-Paul Sartre strongly attractive. He agrégated in philosophy in 1948.

George Kuchar (August 31, 1942 – September 6, 2011) was an American underground film director, known for his "low-fi" aesthetic.

Kuchar trained as a commercial artist at the School of Industrial Art, now known as the High School of Art and Design, a vocational school in New York City. He graduated in 1960 and drew weather maps for a local news show. During this period, he and his twin brother Mike Kuchar were making 8mm movies, which were showcased in the then-burgeoning underground film scene alongside films by Andy Warhol, Kenneth Anger, and Stan Brakhage.

After being laid off from a commercial art job in New York City, Kuchar was offered a teaching job in the film department of the San Francisco Art Institute, where he taught from 1971 until early 2011.

In San Francisco, Kuchar became involved with underground comics via his neighbors Art Spiegelman and Bill Griffith. They both wound up in his movies and George wound up in their publications.

George Kuchar directed over 200 films and videos (including over 15 with his twin brother Mike), many of them short films by students in his courses at the San Francisco Art Institute. His video work is archived at the Video Data Bank and Electronic Arts Intermix. In the Critics' Poll of the 100 best films of the 20th century, appearing originally in The Village Voice (4 January 2000), Hold Me While I'm Naked was ranked 52nd.
