browse v.

Old English breost "mammary gland of a woman, bosom; the thorax or chest, part of the body between the neck and the belly; mind, thought, disposition," from Proto-Germanic *brust-/*breust- "breast" (source also of Old Saxon briost, Old Frisian briast, Old Norse brjost, Dutch borst, German brust, Gothic brusts), perhaps literally "swelling" and from PIE root *bhreus- "to swell, sprout" (source also of Middle Irish bruasach "having a broad, strong chest," Old Irish bruinne "breast").

The spelling conforms to the Scottish and northern England dialectal pronunciation. The figurative sense of "seat of the emotions and affections, repository of designs and secrets" was in Old English. Breast-plate "armor for the front of the body" is from late 14c. Breast-pump is from 1821.

1845, "animal which browses," agent noun from browse (v.). From 1863 as "person who browses" among books. In the computer sense by 1982.

The first browser was invented at PARC by Larry Tesler, now a designer at Apple Computer. Tesler's first Smalltalk browser was a tree-structured device. It enabled programmers to hunt quickly for items in a Smalltalk dictionary. [InfoWorld magazine, vol. v, no. 4, Jan. 24, 1983]
