Peter Thatcher derives his descent in a direct line from the Reverend Thomas Thatcher, the first minister of the Old South Church, in Boston, who at the age of twelve years left England with his uncle Anthony, and arrived in New England in 1635.

Peter Thatcher was born in Attleboro, Massachusetts, July 20, 1812. At the age of nineteen, not liking his father's business of farming, he announced his intention of seeking other means of livelihood, and, sorely against his father's wish, he set out in search of fortune. Two days after leaving his father's roof, he found employment with a house-carpenter, in Taunton, Massachusetts, to whom he engaged himself to work one year for forty dollars and board. After two years service in this employ he, in November, 1834, commenced work on the Boston and Providence Railroad, laying track, in the employ of Messrs. Otis & Co. His industry and ability attracted the attention of his employers, and he was retained and promoted by them, remaining in the employ of the firm and their successors, railroad building, until 1850, with the exception of three years spent on Fort Warren and Fort Independence, in Boston Harbor, where he superintended the work of construction under the supervision of Colonel Sylvanus Thayer. During his career as a railroad builder he was engaged on the principal railroads on the sea-coast from Maine to Georgia.

In 1850, the firm of Thatcher, Stone & Co. was formed, for the purpose of building bridges, both in the eastern and western States, an office being opened in Springfield for the former, and another in Cleveland for the latter. In 1851, this firm was dissolved and that of Thatcher, Burt & Co. formed. The patent for building the Howe Truss Bridge in the States of Ohio, Indiana, Kentucky and Michigan was purchased, and nearly all the original railroad bridges in Ohio, with the depots and engine houses, together with many in other States, were built by this firm.

After having for thirteen years carried on the bridge building business, and added to it a trade in lumber, the firm built the Union Elevator, in Cleveland, and the new firm of Thatcher, Gardner, Burt & Co., commission merchants and produce dealers, was formed. This firm was dissolved in 1865, by the withdrawal of Mr. Thatcher.

About this time a company was formed for the purchase of a patent obtained for the manufacture of a durable paint and fire-proof mastic from prepared iron ore. Mr. Thatcher was chosen president of the company which at once entered on a vigorous prosecution of its business and has succeeded beyond the anticipation of its projectors. The paint is made of Lake Superior iron ore, ground fine and mixed with linseed oil, with which it forms a perfect union. It is then used in a thin state as a paint for surfaces, whether of wood stone or metal, exposed to the weather, and in a thicker state for a fire-proof mastic. The ore is crushed with machinery of great strength, and about three tons of the paint are produced daily, besides the mastic, and find ready market.

In connection with the above Mr. Thatcher has recently purchased a patent, obtained by Mr. Ward, for the manufacture of "Metallic Shingle Roofing," which is now being perfected and introduced to the public, and which, its inventor claims, will supercede all methods of roofing now in use for cheapness, durability, weight and effectiveness.

Mr. Thatcher has long been identified with the Masonic order, and has filled high positions in that body. He is Past M. of Iris Lodge of Cleveland, Past H. P. of Webb Chapter, has been Treasurer of Iris Lodge for ten years, Past D. G. H. P. of the Grand Chapter of Ohio, and is now Grand Treasurer of the Grand Commandery of Knights Templar of Ohio, which position he has held six years.

Mr. Thatcher is a genial, whole-souled man, having a host of warm friends, and has enjoyed the respect and confidence of all with whom he has been connected.
