| Robert Owen | Introduced provision for rest to cover effects of fatigue in 'time allowed'. | Interested in layout and improved methods. |

| Frank R Gilbreth (1869 - 1924) |
Intensive study of 'motion' involved in work tasks which resulted in evolving 'principles of motion economy'. Also investigated fatigue and its elimination. (His wife, Lillian, a pathologist, co-operated with him in this work and carried on with it after his death). | |
| Henry L Gantt (1861 - 1919) |
Originator of the Gantt chart - a visual display based on time rather than dimensions, weight etc. Useful tool when planning loading on a layout and deciding equipment necessary to meet the planned factory load. |

| Charles E Bedaux | Previous to Bedaux, time study composed simply of average elapsed time for each element; Bedaux introduced Rating Assessment. As each element was timed it was given a rating value for speed and effectiveness with which each element was carried out. A Rest Allowance was also included. | |
