Thomas Davenport witnesses Joseph Henry's electromagnet operating at the Penfield and Taft iron works in Crown Point, New York. This experience sparked his interest in electricity, which Emily subsequently supported.

Emily actively supported Thomas's initial experiments. This likely included assisting with the construction of equipment, providing encouragement, and contributing financially to the extent possible within their means.

Thomas developed one of the first functional DC electric motors. Emily's role during this period involved providing a stable home environment while Thomas was engrossed in his work. She may also have assisted in some of the hands-on aspects of the invention.

Thomas Davenport applied for a patent of the electric motor. Emily provided support and maintained the household. The patent was granted.

Thomas demonstrated his electric motor publicly. While Emily's direct involvement in these demonstrations isn't always explicitly documented, it is highly probable that she played a supporting role behind the scenes, helping to manage logistics or assisting with public relations. The early demonstrations were not successful financially.
