Robert Hues

Robert Hues, who lived from 1553 to 24 May 1632, was an English mathematician and geographer who graduated from St. Mary Hall at Oxford in 1578 and studied navigation at a school set up by Walter Raleigh. During a trip to Newfoundland his observations led him to doubt the published values for the variation of the compass. Between 1586 and 1588 he sailed with Thomas Cavendish on a circumnavigation of the globe, making astronomical observations and taking latitudes, and he joined Cavendish's second voyage from 1591, observing in the South Atlantic and measuring compass variation until Cavendish died in 1592. In 1594 he published the Latin Tractatus de globis et eorum usu, a treatise on the use of the globes made by Emery Molyneux, which went into at least twelve other printings in Dutch, English, French and Latin.
