But in historical times, and especially in the centuries since the Renaissance, there have been many inventors, and it will be interesting to see how the things they invented got their names. The word _inventor_ itself means a "finder," and comes to us from the Latin word _invenio_, "I find." The greatest number of inventions have been made in the last hundred and fifty years. The printing-press was, of course, a great invention of the fifteenth century, but it was simply called the _printing-press_, and did not take the name of its inventor. Yet this was a new name too, for the people of the Middle Ages would not have known what a printing-press was. Several early printers have, however, had their names preserved in the description of the beautiful books they produced. All lovers of rare books are admirers of what they call _Aldines_ and _Elzevirs_--that is, books printed at the press of Aldo Manuzio and his family at Venice in the sixteenth century, and by the Elzevir family in Holland in the seventeenth century. We speak of a _Bradshaw_ and a _Baedeker_ to describe the best-known of all railway guides and guide-books. The first takes its name from George Bradshaw, a map engraver, who was born in Manchester in 1801, and lived there till he died, in 1853. In 1839 he published on his own account "Bradshaw's Railway Time Table," of which he changed the name to "Railway Companion" in the next year. He corrected it a few days after the beginning of each month by the railway time sheets, but even then the railway companies sometimes made changes later in the month. In a short time, however, the companies agreed to fix their time tables monthly, and in December 1841 Bradshaw was able to publish the first number of "Bradshaw's Monthly Railway Guide." Six years afterwards he published the first number of "Bradshaw's Continental Railway Guide." The famous series of guides now called _Baedekers_ take their name from Karl Baedeker, a German publisher, who in the first half of the nineteenth century began to publish this famous series. Members of Parliament still speak of the volumes containing the printed record of what goes on in Parliament as _Hansard_. This name comes from that of the first publisher of such records, Luke Hansard, who was printer to the House of Commons from 1798 until he died, in 1828. His family continued to print the reports as late as 1889, and though the work is now shared by other firms, the name is still kept. Not only books but musical instruments are frequently called after their makers. The two most famous and valuable kinds of old violins take their names from the Italian family of the Amati, who made violins in the sixteenth century, and Antonio Stradivari, who was their pupil. An _Amati_ and a _Stradivarius_, often called a "Strad" for short, are the names now given by musicians to the splendid old violins made by these people.
