20314 Johnharrison           Discovered 1998 Mar. 28 by J. Broughton at Reedy Creek Observatory.
John Harrison (1693-1776) was an English clockmaker who worked for decades on the problem of finding longitude at sea, developing a portable timepiece of unprecedented accuracy. This was a great step forward in improving maritime safety and enabled the charting of the world's oceans.
