The First National Bank of Mercer was one of the pioneer institutions of the kind organized under the banking laws enacted by Congress at the height of the Civil war excitement of 1863. Its charter was granted April 19, 1864, and Archibald McKean, its venerable president of today [1909], but then a vigorous young man of thirty-eight, engaged in the drug trade, was among the foremost in its founding and organization. He has been a member of its board of directors from the first, and in 1898 was elected president of the bank. The original capital of the First National Bank was $60,000 and its incorporators A. G. Egbert, A. S. Burwell, Alexander Thompson, John R. Hanna, A. J. McKean, C. W. Kline, S. Griffith, John Trunkey, T. R. Sheriff, L. Beach, R. M. J. Zahniser and Joseph Forker. Mr. Egbert was its first president, Mr. Hanna its first cashier and L. Hefling its first bookkeeper. During its existence the bank has had only seven cashiers—John R. Hanna, O. L, Munger, W. C. Alexander, C. S. Burnell, William Miller, Jr., Charles McKean and C. G. Williams. The present directors of the bank are as follows: A. J. Mc Kean, Herman Frankel, W. C. Alexander, B. A. Williams, J. T. Reed, W. J. Logan, R. R. Wright and S. S. Mehard. In 1875 the capital of the First National Bank of Mercer was increased from $60,000 to $120,000, and according to its last statement made in 7908 its capital remains at the latter figure, while its surplus and profits amount to $165,000.
