Utah was still in the period of its earliest development when Isaac Smith entered upon life’s pilgrimage within the borders fo the state. He was born at Brigham city, December 31, 1857, a son of Samuel and Sarah Jane (Inghram) Smith. Who were natives of England, the former born in London and the latter in Worcester. Becoming pioneer residents of Utah, the father was for many years county judge of Boxelder county and was a very prominent and influential citizen, connected with many public enterprises.
Isaac Smith when fourteen years of age had largely mastered the cabinetmaker’s trade and then went out with a surveying party as peg boy. He soon was advanced to the position of rod man and in that capacity went on a surveying trip with Joseph A. West when the Utah & Northern Railroad Company was making a survey through Bear River canyon to Soda springs. When about sixteen years of age he had charge of the level party under Joseph A. West in making the preliminary survey for the railroad to Black rock and to E. T. City, west of Salt Lake. On his return to Brigham city he was given charge of the Brigham Cooperative Lumberyard and served in that capacity until the fall of 1876, when he went to Salt lake to attend the university. He there pursued his studies during the first and last quarters and during the two winter quarters taught school in order to earn the money to meet the expenses of his course. On account of impaired health, however, he was obliged to seek outdoor work and during that summer was employed at the Brigham Cooperative Steam Mill, shipping lumber and acting as bookkeeper.

He was assigned to the Herefordshire and Bedfordshire districts, where he labored until the spring of 1879, and was then sent to the Channel Islands, spending about three months on the island of Jersey. Later he was appointed president of the Leeds conference, where he remained until April 10, 1880. When he returned to Brigham city.

He was invoice clerk with Zion’s Cooperative Mercantile Institution, having charge of the grocery, hardware and crockery departments and later of the clothing department. He also went upon the road as traveling salesman for the house for five years and later conducted a branch store on Main street in Logan. On the 3d of August, 1890, he was sustained as second counselor to Orson Smith, president of the Cache stake.
