DESCRIPTION:The long-awaited James Webb Space Telescope is planned for lau
 nch by Oct. 31\, 2021. With its 6.5 m deployable primary mirror\, and came
 ras and spectrometers covering 0.6 to 28 µm\, it promises extraordinary i
 mprovements in observing capabilities. Webb will be able to observe the fi
 rst objects that formed after the Big Bang\, the growth of galaxies\, the 
 formation of stars and planetary systems\, individual exoplanets through c
 oronography and transit spectroscopy\, and all objects in the Solar System
  from Mars on out. It could observe a 1 cm2 bumblebee at the distance of t
 he Moon\, in reflected sunlight and thermal emission. I will review the ob
 servatory capabilities and planned observing program\, and illustrate the 
 history of the concept from 1988 to now. The Webb is a joint project of NA
 SA with the European and Canadian space agencies. Europe is providing the 
 Ariane 5 launch vehicle and the near IR spectrometer (NIRSpec)\, and Gilli
 an Wright at the UKATC in Edinburgh led the construction of the Mid Infrar
 ed Instrument (MIRI).
