Aristid Lindenmayer (November 17, 1925 _ 1989) was a Hungarianbiologist. In 1968 he developed a formal language that is today called L_Systems or Lindenmayer Systems. Using those systems Lindenmayer modelled the behaviour of cells of plants. L_Systems nowadays are also used to model whole plants.

An L-system or Lindenmayer system is a formal grammar (a set of rules and symbols) most famously used to model the growth processes of plant development, though able to model the morphology of a variety of organisms.
L-systems were introduced and developed in 1968 by the Hungarian theoretical biologist and botanist from the University of Utrecht, AristidLindenmayer (1925–1989).
Lindenmayer systems are also popular in the generation of artificial life.
