The people who discovered how to make metal weapons instead of the stone weapons which early men used were great inventors too; and those who discovered how to grow crops of corn and wheat, and so gave new food to the human race. But all this happened in times long past, before men had any idea of writing down their records, and so these inventors have not left their names for us to admire.

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.

The names of many flowers have been taken from the names of persons, and this still goes on to-day when new varieties of roses or sweet peas are called after the person who first grew them, or some friend of this person. These modern names are not, as a rule, very romantic, but some of the older ones are interesting. The dahlia, for instance, was called after Dahl, a Swedish botanist, who was a pupil of the great botanist Linnæus, after whom the chief botanical society in England, the Linnæan Society, is called. The lobelia was so called after Matthias de Lobel, a Flemish botanist and physician to King James I. The fuchsia took its name from Leonard Fuchs, a sixteenth-century botanist, the first German who really studied botany.

There are many more new things and names to-day than in earlier times, names which our grand-parents and even our parents did not know when they were children. We talk familiarly now about aeroplanes and the different kinds of aeroplanes, such as the monoplane, biplane, etc. But these are new names invented in the last twenty years. Some of the names of airships and aeroplanes are very interesting. The Taube, for instance, is so called from the German word meaning "dove," because it looks very like a bird when it is up in the sky. The great German airships called Zeppelins took their name from the German Count Zeppelin, who invented them; and the splendid French airships called Fokkers also take their name from their inventor, and so does the Gotha—name of ill-fame.
