He published a number of important maps relating to the Gold Rush, including the 1851 New Map of the Gold Region in California and Map of the Southern Mines. He later partnered with publisher Warren Holt to produce an important sequence of large format maps of California issued between 1869 and 1878. After a long and distinguished career as a California surveyor and civil engineer, Gibbes took a position as curator of mineralogy at the California Academy of Sciences in San Francisco.

Samuel Benton Linton (1838 – August 28, 1927) was a mapmaker, draughtsman, and lithographer active in Philadelphia in the second half of the 19th century. Linton was born at Spring House, Montgomery County, PA, in 1838. He entered the army where he was trained as a draughtsman and assigned to the U.S. Coast Survey. During his tenure with the Coast Survey he completed an important map of Hawaii. Although, like most Coast Survey Men, Linton supported the Union, on a visit to his sister in Richmond near the end of the war he was impressed into the Confederate Army. He refused to fight against Union soldiers and was instead assigned to the Engineering Corps, to which his talents were better suited. As an engineer he created a detailed plan of the Battle of Chickamauga (September 18-20, 1863). Unfortunately, with his name attached to a known Confederate Battle Plan, Linton was unable to resume his duties with the U. S. Coast Survey. Instead he relocated to Philadelphia where he established himself as an engraver and lithographer. He produced a number of maps for various publishers including Warren Holt's important maps of California. During this period Linton maintained offices at 148 1/2 South Fourth Street, Philadelphia, PA. Around 1877 he relocated to Chester County Pennsylvania to take a position as a school director.
