Welcome to the Webster Signature Database, a repository for information about people who made and signed scientific instruments preserved in collections worldwide.

Important note: Most of these instruments are not in the Adler collection (which you can find more information about here). We know nothing about them beyond the information returned by searching this database. You may be able to learn more by contacting the institutions in the "Instruments" column, or by consulting the "References" listed.

Use the search form below to find entries in the database. See About the Database for field definitions.
