Hoen lines mechanically cut through a ground of var- nish to the surface of the stone. A modification of this process played a conspicuous role in the work of the firm up to the introduction of photo- lithography. In the technique of map symbolism Hoen made a contribution of much importance in the sci- entific representation of formations on geological maps by devising a logical system of rulings and patterns in each of the several colors, so that, from the standpoint of printing, the number of impressions could be reduced, it being possible to differentiate subdivisions of the geological pe- riods within the group horizon while showing by the group color the period relationship. The first application of this symbolism was made in the maps, printed by A. Hoen & Company, which accompanied R. D. Irving's The Copper-Bearing Rocks of Lake Superior (Monographs of the United States Geological Survey, vol. V, 1883), Shortly after the publication of this work the same principle was embodied in the United States Geological Survey's patterns and color conven- tions for geological maps (carried to its full fruition on the "Geologic Map of North Amer- ica," i: 5,000,000, engraved and printed by the Geological Survey; see Bailey Willis, Index to the Stratigraphy of North America, United States Geological Survey Professional Paper 71, 1912). In the more than thirty years since Weber's death the establishment had steadily grown in size. In 1882 a large building was erected on Lexington, Holliday, and North Streets. In 1901 this was destroyed by fire, after which the plant was removed to its present situation at Chester, Chase, and Biddle Streets. Nearness to the to- bacco and cotton industries led to the founding in the eighties of a branch in Richmond, Va., for the printing of labels. The Baltimore plant num- bered about 200, the Richmond branch about 125 employees. On the death of Hoen in 1886 his son Albert Berthold Hoen took over the car- tographic activities of the firm. The outstanding traits of Hoen's character were idealism, enthusiasm, and appreciation of the good in others. His tastes ran to the fine arts, music (he played the violoncello himself), and horticulture. He took a lively interest in the suburban village of Waverly, of which he was one of the first settlers. He appreciated the advantages of city planning and, through the County Commissioners, had surveys made of the metropolitan district of Baltimore to provide for the laying out of boulevards and for the growth of the city. In February 1849 he mar- Hoenecke ried Caroline (Muth) Weber, the widow of his former associate. IThe Biog. Cyc. of Representative Men of Md. and the District of Columbia (1879) J biography of F. N.

He graduated from the Branden- burg Gymnasium, studied theology at Halle, and became a tutor in Bern, Switzerland. He was ordained Nov. 18, 1862, and sent by the Berlin Missionary Society to Wisconsin, where he be- gan work at Farmington, near Watertown, in 1863. In 1865 he was married to Mathilda Hess, daughter of the Rev. Rudolf Hess of Hochstetten, Canton Bern, Switzerland. The following year he was made professor and director of the theo- logical seminary of the Wisconsin Synod at Wa- tertown, but in 1870, when the school was com- bined with Concordia Theological Seminary, St. Louis, Hoenecke declined, on a plea of poor health, the call to St. Louis. Instead, he accept- ed a call to St. Matthew's Church, Milwaukee. In 1878 the Wisconsin seminary was brought back and located at Milwaukee, chiefly to permit the pastor of St. Matthew's to serve as director and professor of homiletics and dogmatics. In 1890 he resigned from St. Matthew's, and on Sept. 17, 1893, the Evangelical Lutheran Sem- inary, as it was called, moved into its permanent quarters at Wauwatosa, a suburb of Milwaukee. This seminary was but the lengthened shadow of its great president and professor. As a preacher and homiletician he ranks high. His lectures and sermons were brilliant and stir- ring expositions of the Gospel. For the general reader he issued the Gemeindeblatt, and in 1903 he founded the Theologische Quartalschrift in which appeared his numerous articles and the sermon outlines later republished as Predigt- Entwurfe Uber die Altkirchlichen Evangelien und Episteln nebst einigen Freitexten (1907). The only other book issued during his lifetime was the sermon collection, Wenn ich nur Dich habe. His sons, Walter and Otto, edited at the request of the Wisconsin Synod his lenten medi- tations, Bin L'dmmlein Geht und Tragt die Schuld: Zwei Reihen Passionspredigten (1910), and his great Dogmatik (vols. I, II, and IV, 1909; vol. Ill, 1912; index volume, 1917). As theologian and dogmatician Hoenecke showed a high-minded conservatism. At a time when furious doctrinal battles were raging on 108
