JOHN I. JACOB, deceased, was born in Baltimore, Md., in 1778, and died in
Louisville in 1852.  He came to this city about 1807, and engaged in the
mercantile business, forming a partnership with Thomas Prather, one of the
most prominent of Louisville's early business men.  The old house of
Prather & Jacob was for many years one of the reliable business houses of
the young city, and was the synonym for all that was upright and honorable.
After the dissolution of their partnership Mr. Jacob became president of
the Branch Bank of the United States, and after it was closed was made
president of the Bank of Kentucky, which position he resigned in 1836.  He
was for a number of years a member of the city council, and in 1848 he
became president of the Louisville & Frankfort Railroad, which was fully
completed during his administration; but the infirmities of age compelled
him to resign the position and retire from active business.  He aided in
the establishment of the asylum for the blind, and contributed greatly,
in various ways, not only to the growth and prosperity of Louisville, but
also to the amelioration of the condition of the poor and needy, displaying
a liberal hand in the great charities of the city.  From time to time he
had purchased property throughout the city, which rapidly increased in
value, and, by well conducted, legitimate business, he accumulated a large
fortune.  Mr. Jacob was twice married: first to Miss Ann O. Fontaine.  The
children by this marriage were: Mrs. Curran Pope, Mrs. John W. Tyler and
John I. Jacob, Jr.  His second wife was Lucy Donald Robertson.  They had
eight children, of whom there are now living--Mrs. James B. Clay, of
Fayette County; Col. Richard T. Jacob, ex-lieutenant governor of Kentucky;
Thomas P. Jacob, president of the Kentucky & Louisville Mutual Insurance
Company, and Hon. Charles D. Jacob, mayor of Louisville.  Of his first
wife's children, only Mrs. Tyler is now living.
